Just thought I would check in. Sounds like your doing okay. If it were me if your H called, I would say "you left? Didn't know you were gone." he he. If he blames you, oh well just agree. Say why yes it is all my fault. I would just let it go for a while and let him see for himself it isn't all you. The more you let it known it makes you angry he left or that you want him, the longer he stays gone. They always think it all is honky dorey on the other side. Till reality sinks in. I always act as if I don't care. The threats to leave...I say well go on. I don't show I care cause I show I can make it with or without him. I don't have to have him....may want him...but don't have to have. I am better then fighting with ow.....let ow make the fool of herself, the demands all of that. H will then want to dominate someone and ow may not take it too well.
Your gameplan should be to show your secure in yourself. That your strong and your capable. If he belittles you, say you gotta go. Don't listen to it. He knows it gets to you. If your not listening it will drive him batty. You don't have to listen to it and by not doing so hopefully it could change his ways a bit by not doing it. You stay on when he is nice get off when he isn't.
Anyway it sounds like from what you wrote your h is seeking what he lost or gave up. His football scholarships could be it. You know when you get to a stage of life and you wish you could of done this or that b4 and wonder....well I wonder if that is what your h is doing.
