Sounds like he is caught up.......in love with you and doesnt have a clue what to do to get your attention.....
just walk right up to him and ask him what's the deal ...only do this when you are looking hot and feel confident and have the right attitude to carry this bold thing off :)
look your best,smell lovely and go girl !!!
exes and custody is an area i try to leave alone. it's a volatile situation with a different side for everyone involved.
It sounds like he is desperately in love with a woman who betrayed him and doesn't know what to do to get her back so he is trying anything he can, or it could be something else, I don't know but it wouldn't take me long to figure it out with more details.
Wants the woman to be jealous. Maybe confront him and tell him you don't care about him anymore (if that's the case). Or, tell him you're willing to take him back (if that's the case).
