I believe we lose a part of ourselves every time we lose anyone who is close and important to our lives wether in a long or short relationship. It's good to have friends and family that is if they haven't abandoned you. I tend to go on nature retreats, camping, hiking just to feel the love of nature, nature is a great remedy to find yourself and start over.

That's a good damn question. I think sometimes looking back on a failed relationship ppl tend to have blinders on and only reminisce about the good times and forget about the bad times.
At least that's my problem.

Just some thoughts I've had on this issue. We often mourn "what could have, should have been" too often as much as what really occurred. Knowing that has helped me a great deal but it wasn't until only recently that line of thought has become forefront in my mind.
I don't allow someone to rest on laurels of "best foot forward stage" anymore when stuff goes sideways. There is NO ROOM FOR ERROR early on. NONE. I don't want to look back & kick myself for ignoring an elephant that was there from the beginning because funs were happening.

I've this idea more so about what I don't want with equal weight to what I DO WANT.
It takes quite a bit of effort on someone else's part for me to decide to accept warts & all, but once that happens...yes I'm capable of moving heaven and earth for someone.

Until then refuse to be stuck in 1st or 2nd gear with anyone.

As an aside I had this crackhead idea that stuff would be easier, people would be mellower and more prone to enjoy someone's company without so many "games" than when we were younger. Boy was I wrong. sigh. I'm just going to keep in the forefront of my mind that at my age the exchange rate is forever not in my favor and going to be extremely cautious... tho I'll flirt with abandon until being cuffed again with the assumption it's never going to happen.

Who can explain love. I'm still in love with someone that broke it off with me almost sixty years ago.

I don't think its to get over someone its why did I stay with the person so long. All the things that was wrong with them

Even now, 13 years later and happily married, there's not a day that I don't think of the "One" that got away.

Everyone's different but I found it generally took as long to really get over it as the relationship lasted and I used that as a rule of thumb.

I am a bad person. I can get over them pretty quick.
If they call it quits, or I have had enough, it is a decision in my mind. That's it. I move on.

Too many people seem to dwell on the past.

I agree that part of why we miss someone who wasn't right for us is that we fell into a habit, be it a good habit or a bad habit, and that can be hard to break. Maybe get into a new routine or hobby that keeps your mind going another direction? It's okay to grieve for a relationship even if it was a bad one... there are always some good aspects of a relationship, even if there are some dealbreaker aspects that cause a breakup.

I have been devastated since the first of the year when my boyfriend unexpectedly died. I'm just getting on with my life after six months. Life is too short to waste.

They say diversions are good. Others say, wallowing deep in the despair will help get it over soon.

Whatever: NEVER GET A FUCKING PET!

When we have real feelings, it takes time to grieve. Be kind to yourself...healing will come.

That's a good question. Could it be habit? You are used to thinking of them (good or bad) and the habit is hard to break. Also, I've noticed, in trying to get my ex-wife out of my head, that it's useful to find someone else to think about, even if it's an imaginary relationship. Of course, that imaginary relationship has to have some sort of emotional weight, or it's just an airy dream.

It's like having a virus that takes months/years to run its course.

Not sure, never dealt with that before, I just move on if a relationship goes south.
