Unfortunately, I think you should make a clean break. When things are done, they're done..

Sorry for what you have been going through. Has something been going on with him at work or his family where it could affect his behavior?

If he is unwilling to communicate, you might need to do some detective work. Talk to his friends, family, or coworkers. Find out if something is going on that he might be embarrassed (or ashamed) to talk about with you.

You might want to consider a trial separation to see if things can be worked out; if he wants to work things out. If not, the relationship could be over. Sorry.

What did you do to ruin a wonderful 6 year relationship?

How to discuss the problem of communication with someone that doesn’t listen. I don’t know. That’s quite a riddle. Good luck. I hope you the best.

A few months doesn't seem long compared to almost 6 years of good. I would find a nice quiet relaxed time to try to get to the bottom of it. And, perhaps acknowledge that he might not be ready to talk, but ask that he does soon.

I spent 31 years in a marriage that was broken at 27 years. Sounds like he may have found someone else. As someone else said if you still love him try to get him to talk. If not, my advice is not to waste much more time and move on. Time and life fly by..

The 7 year itch is a real thing. It's the point in the relationship when your partner feels trapped, that he is missing out on things he'd be able to pursue if not for you, and his resentment grows each day. Sometimes it blows over, and your relationship recovers to be stronger than ever. When is it beyond salvaging? When you find yourself unable to swallow any more of his crap. Everyone has a different point of no return. Taking the step to separate yourself from the drama isn't easy, especially if there are children involved, but the old saying here applies, if you think you have a problem, you probably do. That's all I got. See a counselor by yourself, if he won't join you. My ex decided to move out just about 10 years ago, after 28 years of marriage. I let her go without a fight, best move I've ever made. Good luck, DNB.

I'm sorry you are going through this. =[

A number of people have mentioned pregnancy in this comment thread but I see nothing in your post to suggest that. If he has had such a major attitude shift in a relatively short period of time my guess is that something is wrong (yeah, I know, stating the obvious). If you have tried to pin him down on what's bothering him or what "issues" he may have in the relationship in the spirit of trying to fix things and he is not responding to you, it could be he has already checked out.

If that's the case you may not be able to change it, and probably shouldn't want to. Why fight for someone who doesn't want to be with you? If he really is done, it would be nice for you to at least know what his deal is.

You would love my collection if arrowheads and stone tools i have found scouring the riverbanks and such

I don't know that I have anything to add to what other commenters have already said advice-wise. Sorry to hear you're going through that.

I hope you're able to figure out the best decision for you both, in the near future.

That's difficult to say. Being In Love with someone and Loving them are two very different things. So I just hope things get better for YOU, either way.

Do u love him ? If the answer is yes , sit down w self first and discuss w self ( pen and paper ), what bothers u . What do u want / need / hope . Then write as well what u need / want / hope for u both . Hand him over the paper and give him a two weeks to think about and respond . Be ready to walk away if he ignores your request or laughs at u or no meaningful talk comes out of this . 6 years is 6 years . Take 6 trips somewhere if u can afford . And turn the page . No fear . Better alone than alone w company . Better alone than becoming a pet or a pest . My opinion . Good luck .

He is not interested in his relationship with you . Sounds like , he's found someone who he thinks makes him feel better about himself . He has no intention of making you feel good about your relationship with him . Prepare to stand on your own two feet .

I'm sorry you're going through this. I don't have any words of wisdom other than being pregnant is stressful enough without have to be tweaked this way.
You should be able to relax & do the "nesting" thing, celebrate your condition and be getting as much rest as you can. This should be made to be a happy time you both can look back on.
(((( hugs )))
I hope he "wakes up" for you.

Nothing last forever. Cliche as it sounds but that's the way it is.

I tried for ten years and it was all lost time that I can never get back.

I would say to him that you feel he is no longer invested in the relationship and ask him if he wants to call it a day. No preamble where he can avoid the conversation, just come out with it.

Depends on how long you've been together. Six years is a pretty strong investment. OTOH, if you had just met him last week, then CYA. Certainly no one suddenly loses "communication skills" or ability to listen. Somthing has caused a road block that has brought out this characteristic in him that's always been there, but was not relevant to yr relationship. If you hope to save yr relationship, you need to figure out what that is, and more importantly, need to make him understand it.

I hung in there too long for the first two long terms...well it seems like it was too long, but I think that we are in it until the time is right for it to end. The 3rd (and last one so far!), I didn't wait so long, once the red flags were popping up all over the place! I have learned to not tolerate being disrespected in any way. After trying to communicate openly about the issues, if they are not willing to own their actions, not willing to work on the issues, it's time to kick em to the curb. Stand your ground, you deserve to be treated with kindness and love and RESPECT.

I have wasted years throwing time and energy down this "proverbial rathole" to no avail. Nevertheless, if your heart is still in the ring, it is probably worth a rry...but not an endless try. You have to be realistic

I'm sorry to have to say this but he has already left mentally, he is just waiting to leave physically ; maybe hoping you will force the issue.

An abrupt personality change can mean anything from cheating to mental or physical illness. I would have what my grandma would have called a "come to Jesus meeting," meaning a pull-out-all-the-stops confrontation. I wish I had done that before actually catching my husband in the act. By then it was too late.

As a member of the enemy (men) I shall claim you a hero for putting up with this. Get some , claim some , go to bed. That’s a way to live.

Are you kidding? He's obviously already left the relationship.

Time to cut your losses, tell him "things aren't working out" and ask him to leave, then block and delete him from all social media, tell people who ask about him that "things didn't work out," and if he resists, put his stuff on the lawn and change the locks.

That's sad. Is he stressed out & depressed, or showing signs of moving on? Good on you for trying to save the relationship, 6yrs means a lot.
