I think it depends on the context

I'll let everyone know as soon as I find someone to date.

it depends on the circumstances. from previous experience it never bothered me. but those were not more than brief mention or comparisons. so that was enough for my desires.

I welcome it, especially early on. I watch what he says about the ex. If everything is her fault, that's a huge red flag.

i have to say 'other'.
there can be a lot to be learned about a person from the way he/she talks about past (or present, for that matter) relationships, as well as what this person has to tell - & that i want to know.
on the other hand i get quickly bored to tears with non-adventurous life stories, especially if they are still emotionally loaded.

The ex and I were together over 20 years, so it would be impossible not to talk about that phase of my life. I don't rant and rave, and I don't overdo it. I don't know how you could get to know someone new and not talk about your past.

Just enough that I learn their earlier experiences, yet not so much that it's monotonous.

It depends on what / how is being said.

It strongly depends on how they are talking about it.
Sharing parts of personal life experience is pretty much fine. Comparing (even if positive) is not.

When I was dating my 'late' partner I did mention a 'former' one but was told sometimes it was a little too often. So I learned a lesson. Now I have to have a balancing act as to just the right amount. Other person(s) are a part of one's life as one's friends and maybe even their children and one should not expect the other to forget their past. For me, I want to know about the other people in a persons life, that's part of a relationship. The problem arises when that relationship is used as a comparison or model or chip on one's shoulder. For me I do not want to replace any of my past partners even the great one. I want someone new. It is not fair to anyone and is unrealistic. Everyone should be judged on their own merits. BTW I would hope if I did talk too much about another in the past my 'date' would nudge me to back off.

Our past accounts for who we have become. Some has been edifying and some damaging. A person who loves who've they become and appreciates others for who they've also become has no difficulty sharing ANY life experiences, joyful, hurtful or teaching. Without the past included who are we?

If it's right out of the gate, there just might be an issue. If it's a lot, there just might be an issue. Over time, a little at a time, it really just isn't avoidable. There are going to be happenings that draw it out. And what better way to become informed of matters that may or may not cause a degree of discomfort in a relationship that could potentially be a benefit. If I had a partner that within our relationship never found that draw as mentioned, I'd be about as worried as the one that couldn't get out of the gate without repeated mentions.

I don't mind as long as its relevant to a story or something

Actually, I think it depends. I am dating a man near my age. We both had long marriages. It would be pointless and too much work to try to pretend our ex-spouses didn't exist. A lot of mention of prior short-term dating experiences might make me react differently.

I don't mind, it is all part of who they are.

You have to care to be jealous

It depends on the context. I dated a lady in Denver whose ex would come hang out with us. I liked him. My ex-wifes' ex came to town and stayed with us for a couple of days to see his daughter graduate, and l liked him better than l liked her. I just don't want to hear them bitch about the ex.

Definately not on first dates don't want to know about your x mkakes me wonder if you are compairing

It's a treasure trove of information! What did they like? What did they not like? How can I make myself the better choice? What should I avoid doing if I want this relationship to last?

Depends. I don't want to hear about all the things the ex did wrong. My first question when the ex blaming starts is "what was your part?" No one is an innocent victim in a bad relationship. If they can't acknowledge the responsibility in the breakup, they're not ready to enter into a new relationship. They'll just keep making the same mistakes again and again.

It's usually a big red flag. I used to brush it off in the past, but I have learned through experience that it is a significant signal that the person has not moved on or put the negative aspects of past relationships behind. In my opinion this behavior can be a sure signal that they will project the actions of others upon you and over analyze your every move based upon their hang-ups about their ex.

Exs are going to come up on conversation as in, "when i went to over there with my ex, ...." or "i realized giving up things i want to do just because my ex wasnt into it is not good for a relationship."

Now if its nothing more than a "my ex bitchfest" yeah, not so much.

I enjoy hearing about it, so long as it isn't all subjectively negative. Meaning, if it is just talking bad about them because they are the 'ex', it makes me think,"What are they gonna say about me if this doesn't work out?" If it is about abusive behavior, I don't mind being a sympathetic ear and trading war stories.

Knowing about past relationships and how they describe them can give me valuable insight into their personality and character traits. The information is valuable to me in determining the future of our relationship. Better to know than be surprised.

I went with "Other". The reason is that it depends on the situation, and ALL of those answers have been true for me at some point or another. The way a person talks about their ex, or chooses not to, can reveal a great deal about their relationship skills, and whether they have healed and learned from a previous relationship and what caused them to fail or otherwise come to an end. It could also be educational to listen and learn to avoid mistakes made by their ex. An ending isn't necessarily indicative of failure and could be a sign of maturity.
