Michelle, honey, I feel so bad for you. I can relate totally. My wife accepts (so far) my life, but wants no part herself. So I go out, just as she spends time with her friends and her church group. I try very hard to limit my outings and to then be as supportive of her as I can when I am at home with her.
Perhaps in time your wife will come to appreciate your needs and come to accept your taking a night now and then to meet others without her? With enough positive reinforcement of your relationship coming from you, do you think this might be possible?
Hugs
Sammie
