Bridesmaid

Have you heard from her about non-wedding stuff or has there been total silence? Is there any way you can call her to find out what's going on? If she hasn't responded at all in nearly six months, then it sounds like you are going to have to drop her from the wedding party. But if she's a close friend (and I'm assuming she is, to have been asked to be bridesmaid) then I would want to speak to her in person first - she may be going through something (mental or physical illness, relationship breakdown etc) that is so overwhelming for her that she is not able to make the effort to get in touch. If she is (or has been) a good friend, I would make the effort to find out if something's wrong before just dropping her.

She's not coming clearly. She is avoiding you for a reason, maybe she got offended or something. Is she picking up your calls or avoiding them also? Try and reach out to her again and ask her to speak about it. If she continues to have no communication with you you will have to take her off as a bridesmaid and possibly the wedding if she has not RSVP'd yet? why would you want to have someone as a bridesmaid if they refuse to have any form of communication with you. I know it can be a bit harsh but you have million other things to worry about, bridesmaids are supposed to be there to help you and not to cause you more drama!
