You could ask yourself if you wanted her there. I thought you said you loved her and wanted the marriage to work? If I understood correctly, then you need to reach out on a limb at times to make her feel welcome.
I did want her there. Part of me asked because I wanted her to come. Part of me asked because it was the polite thing to do. Then she was on the phone all evening. I asked about her friend and showed concern for her.
I just don't know when to "reach out", you know? I try to make her feel welcome, but I don't really see any effort on her part. She is still at home, I believe, because she has no place else to go. Her agreeing to go to the game surprised me and made me happy. Then the "alien" attitude showed up almost instantly. That's why I wonder why she came at all. I tried talking to her and involving her in things. She had no interest. The main thing she was interested in was her damn phone.
