I feel like it is a passive way of warning me how they expect me to act. It is a past relationship for a reason, and more often than not, they are telling me what was unacceptable about the relationship. It's usually better to be vague about past relationships, I think.
I know exactly what you mean.
I don't mind, I personally like finding out about the things they enjoyed or didn't enjoy, and past relationships kind of give you a peek into their previous self.
And about your other question, a 'nice' boyfriend will talk about past bf's with you, if you wanted to, for the same reasons I stated above.
If it comforts them and helps to make quidlines for the current relationship, then it's ok. Also a good learning curve.
I feel like they have baggage.
The superficial stuff, like, " oh my ex had a dog just like that" rs pretty cool. It is nice to share pleasant stories. When it is related to issues that relate to the current relationship, it feels he expects me to be responsible for his baggage, rather than just deal with it himself. "My ex always used to.........." is a cause for concern. My response is, "maybe you need to work through this stuff with a counsellor."
