How to dump a bridesmaid.

I would just tell her that because of David's relationship with the ex-boyfiend, that you're uncomfortable having them both at the wedding. If you're not close to her, she will probably be relieved.

Make it on you, not her. That to cut costs, you need to make the wedding party smaller, or something like that. I agree, she will probably be relieved, it would be awkward to be a bm at this point.

I second Getting excited's idea... However, I do have one thing to add. You said that she was a close friend of your FH's in addition to being his groomsman's girlfriend... I think that if that's the case, your FH should take the responsibility. We had something similar happen... a friend of my FH who agreed to be in the bridal party and then dropped off the face of the earth. He and I discussed it and decided that since it was his friendship, he would be the one to broach the subject. The upside is that it will give him a chance to couch it in terms that will hurt less, and possibly salvage the friendship in the end.

Yup, I say dump it on David lol. I agree w/kate, I think it's his responsibility if it is his friend.

Hrm.... problem with leaving it to David: It'll never get done

I agree with what Excited said. Tell her your uncomfortable having both of them in the wedding and you think it'd be best if she's not. Since you aren't close to her just keep the conversation short and sweet. No additional explanations are needed.

Donald Trump style. "you're fired!"

JK :-)

Has she spent any money on the wedding at this point? If I had I would be a little upset but if I hadnt then I agree it would be a relief to be out of that wedding!

Not yet. thankfully.

Tel her just that! Sorry but.......

I would lie & say that budget wise you can't afford to have a fourth bridesmaid & that you're sorry, but she's the one you know the least.
