You're right,sandi2,the living arrangements are too close but His gone so much at work and school that its almost like he doesn't live there anyway. Besides it seems to work well for the kids for now.
As for dropping the rope for the most part I have. Except for kid related contact I have gotten in touch with him at all and I try to keep that to a bare minimum. The fact he asked us to dinner blew me away.
Another strange thing was when we got there he stayed by the table looking at the menu instead of following the girls to the buffet. I had said I wanted to check the menu first and then went to hang up jackets. Then at dinner He offered to pick up groceries at the military commissary (1/2 hour away) because he would be by there on Wednesday. I made a point of not asking why he was going to be down there. Anyway, that was the evening. It was a nice dinner and I kept my expectations well under control.
As for being tired of the situation, I don't feel that bad about it all the time. I just don't know how to deal with feeling that way occasionally. Is it normal?
