From what you wrote and if he's all honest about his feelings, I think one day you two will end up together........
Right now though, I think the only thing you can do is to just keep contact with him and talk to him if you want to
win him back. And if your ready for it, try to find something out about custody and stuff. You seem really dedicated
to this man and he seems to love you very much. Now I've had friends who have gone through a custody struggle
and it's not pretty, and it's very long. And when it's two people who dislike each other it's even harder. The army
thing sucks cause even if you proved she was an un-fit mother (doing coccaine) and stuff they'd probably wouldn't
give custody to the father unless he A) Quits the Army and finds a stable job or B) Files for divorce marries
someone else (i.e. you) and you go for custody of the child. OR his parents can try for custody......now this is just
scratching the surface.
You love him he loves you. But you could easily get hurt in this situation he could end up staying with her because
of the guilt....and that will leave you broken hearted.
My advice would be to keep in touch with him, get to know him alot better, find out what kind of person he is and
if he is truly just in it for the kid, then later on, if you two want to try to figure out a custody thing you should.
just take it easy, be in his life and be his support......
Please keep me update
I hope this kinda helps!
