My best friend and I have always talked about having each other as our MOH since we met. I got engaged to my FI and we've been together for six months. She on the other hand has been dating a guy for over two years who is still reluctant to even talk about getting engaged much. Now my once supportive, upbeat, and positive best friend has made a complete turn around. She didn't call me for like three weeks after I called and left a message I was engaged. I do not talk to her about the wedding to avoid it but, she continuoulsy makes snide comments about how fast it is, and how her parents would never let her be so dependent on a guy after only six months. Her boyfriend talked about proposing this summer and she has told me she wants to have it mid May when she knows mine is late May. I was trying to be supportive and understanding but I finally yelled at her and she seemed better after that and asked if she could be my MOH. I told her no, but maybe a BM. She was great for a few weeks up until I mentioned we may possibly move the wedding up to this summer (We're not even sure yet) and she went right back to before. At this point I don't even want her to attend as a guest. I really could care less if she wasn't in my wedding party. I have plenty of supportive friends and family and she is the only one who is acting like this. Advice?
