HELP! need advice on BM dilemma

Hello. My BM is a good friend of mine since High school. In the beginning, when I asked her to be my BM, she was really supportive and communicative. But over the past 6 months, she is really hard to get in touch with and very distant. It feels lately that our friendship is one-sided where as I am always the one to get in touch with her and she would never call me anymore. I have complained to her that she doesn't keep in touch anymore and she didn't think it was a big deal. She would never inquire about the wedding. She has been unemployed for awhile and money is tight. I paid for her BM dress and told her to pay when she had a full-time job. I know she has a tough time looking for a job and only had a temp job here and there. I have been understanding abut her situation, help her look for a job, supportive on her carrer path, and pretty much hold her hand the whole time. I have only asked her in her role as a BM is to help out the MOH with planning my bachelorette party. I had my party last Sat night and she was a no show. She left a message on my cell and claimed she had a stomach ache. My MOH said she didn't help much with the planning and was so hard to get in touch with her as well. I have this gut feeling that she is not going to be there for me for my wedding day. ( only 26 days away) I love my friend but she hasn't been communicative or supportvie at all. I have been a very good friend to her especially I been her shoulder to cry on so many times when she needed a friend. Now I need her to be there for me! I want to talk to her asking if she still wanted to be a BM. I know she still hasn't gotten the dress altered, gotten shoes, and I still have to tell her about prices on hair and makeup.

Anyone had similar situation with BM?
what did you do?
Any advice would be great. TIA

I've heard/read so many bad stories about girls who weren't there or created major drama and that's why I didn't have one - just MOH and BM.

I would confront your friend and ask her point blank - are you still interested, or should we part now? Unfortunately, this happens more often then it should - and it's very sad. But you're better off knowing now then the day of.
