There may be several reasons for this. He may not be fully over her yet and talking about her is a way to deal with it. Or maybe he just thinks you're interested in his past. He might also be trying to make you feel good by showing you how much better than his ex you are. He could also be trying to make you jelous to see whether you are a jelous person or to try to prove to himslef that you care about him.
there's a reason they are a ex
how is life what you did when you were with them and stuff
Make efforts to become better than her boyfriend, and she will talk about you to her ex-boyfriend.
doesnt matter if there in it or not. just talk. hes you EX boyfriend. who cared what he thinks.
no
get another boyfriend and make ur ex boyfriend jelous
I think you should talk to your boyfriend and tell him to have a little chat with his ex.
That would depend on several things. Do you talk to your boyfriend about your ex as in things you and he used to do together? Do you talk about him in a manner that would indicate to your boyfriend that you still love, or miss your ex? Do you tell your boyfriend things like, "That's not the way my ex did it"? If so, then it is a problem.
No
you can talk to them.or flirt
If she was real, she will not become an ex.
that she misses him and isn't over him
