Why is my ex bf asking me advice on his new relationship?

I just broke up with my ex bf about 3 months ago now and we had been on and off for a couple of months before we broke up for good. We were together for about 4 years but we were mostly in a long distant relationship and towards the end of the relationship I finally realized he didn't really want to take our relationship to the next level (to move closer together) We have been talking online once in awhile just to chat as friends. But tonight he said he had to talk to me and needed some advice. He went on to tell me that he's back with one of this ex gfs (who cheated on him) and he had slept with her when we had one of our breakups before the real one. And he told me she's pregnant and he thinks he's the father and he wanted advice from me about what he should do. He kept telling me that he wants to be with her and he feels amazing with her. All of this stuff he told me just completely broke my heart and made me very angry and I told him that. He told me details about their sex life and all this stuff that just blew my mind that he would actually tell me this stuff after only breaking up a few months ago.Why is he doing this to me???? I mean, I told him a couple weeks ago that I was kind of seeing someone but that was that, I didn't say anything else.We talked online about this tonight and the whole time I was in tears. I got so mad and upset with him that I yelled at him and told him I wasn't ready to be talking about this with him because I still had feelings for him and it hurt too much.

Either he's trying to make you jealous like the other people think.. or he really wasn't ever serious about you as a girlfriend and thinks of you as just a friend. Someone he can talk to about anything. He might think you know him and will be honest and tell him good advice. Either way it's down right evil to do that. He would have to be a complete moron to think it wouldn't bother you to hear about someone he's wanting to be with and possibly having a baby with. Now you've been honest with him about your feelings so he has to let you know if he is trying to see if your feelings are still there for him or if he's really done with you and moving on. It really doesn't matter if he never tried to move closer and now he may have a child with someone else. I would just give him the best advice I could and stop talking to him.
