Okay so this I'm in a little bit of a predicament and it's a bit of a long story so please bare with me. To start I was asked to be the MOH for a girl that I am friends with, but we are not super close. I am actually great friends with the groom and met her through him. She never calls me to hang out with just her, but we end up seeing each other quite a bit because of the groom. So that's just a little bit of background of our relationship. Now, I am very aware of my responsibilities and I am happy to do them because I am such good friends with the groom, and I truly like both of them. Well, when I was asked to be in the wedding party I was told who all the groomsmen were and was happy to join in on the festivities. Recently, they both told me that they want to kick a groomsman out of their wedding party because he hasn't talked to them in a month and they want to replace him with a guy that I have an extremely bad past with. I use to be best friends with this guy growing up, and in the past couple years he basically became very manipulative towards me, and in the end tried to break up my marriage. He has done such horrible things to me in the past that i have not spoken to him or seen him in a year and a half. I am very uncomfortable being around him. My husband is also very uncomfortable being around him, and my husband is also in the wedding party. So the bride and groom asked my advice about kicking out the groomsman and replacing him with the guy that i don't like,and all I have told them is if they kick out the groomsman to be prepared to lose him as a friend, and if they ask this guy to be in the wedding to be prepared for what comes that. I also said, if this guy ends up in the wedding I would like to talk with him before their big day, because I do not want to cause any conflict that day. Once I said this they both got very defensive and basically started blaming me for the reason why he wasn't asked to be in the wedding in the first place. I do not want to be blamed for them making a mistake with their choices for a wedding party and i don't think its fair to put that burden on me. Also, I have been told by a close friend that the bride was telling her about how selfish i am being and how its her day and i have to just deal with it. It really hurt my feelings that she couldn't talk to me about it and had to go behind my back. This is the brides character because she does not like confrontation. So with all this said, I would just like advice on how to deal with this situation. I do not want to be put in a situation where I am uncomfortable, but I do not want to be a burden on them either. I really want to be a part of their wedding, but am not sure if it's really a good idea at this point. Please help!
