So. My cousin whom is from Germany came to visit and yesterday was the first time he had met her. Well the WHOLE time they were walking side by side talking I was walking next to my grandmother talking to her since they seemed to be interested in talking.. Well my husband never likes going out and doing anything with me ever but when me and him went to target he was all excited saying we need to figure out something to do tomorrow with your cousin. Kinda makes me mad because he never likes going out doing anything with me if I ask to go to the park to walk he's always too busy..and this morning he was like when are we going to go get your cousin?? I asked if he liked her he didn't give me a yes or no answer.... Before she even got here he wasn't interested in meeting her but apparently he wants to be around her all the time now! It's his birthday today and I had plans to spend some time with him alone but he wants to hang out with her..so what do I do? Or say!?🙄🙄🙄
