Why would he need to talk about his ex and their relationship?

OK, does he bring it up or do you?

I bring it up, I am curious about his ex and their relationship

MAybe he just rather not alk about it. I mean, its in hte past...if he can let it go, you ened too as well. Live for now, today nad tomorrow. We can ot change the past, but we can make out future a wonderful thing.....you have this choice. This obviously bothers him, otherwise, he's freely open up and tell you about it. Men don't like to tell all. Why is it you feel you need to know? You have him now....is that not all that matters?

I might add that if you keep bringing up painful memories for him then you just might find yourself without him.

You seem to be insecure about yourself and your relationship with him. You are with him, enjoy it...don't give him a reason to go elsewhere.

Time is precious...why not spend it with him and make memories of your life together and keep the ex out of the time that you two have.

If he was the one bringing it up...then I would be worried.

Let his ex go, he has.

maybe she did something that hurt him so bad he cant talk about it.
he doesnt see or talk to her does he?
i was in a relationship for 4 1/2 years and i found out that my ex was in love with his ex 1/2 our relationship. they talked to each other, and he played daddy to her kids. and this hurt me so much.
