I have this briedsmaid that i ask to be in the wedding durring the summer before several of us went on a vacation together with our mates. I had become good friends with this girl over about 9 months up until the summer, when all of a sudden she total changed well actually changed back to what she use to act like before we were friends but i thought she had just changed for the better when we started to become friends.She was talking about leaving her husband and trying to find a husband that could give her the things she wanted in life like a harley and she wanted to live in the city. She became all about material things and shes the kind of person that when shes unhappy she threatens to leave her husband and then he buys her back (laptop, tiffanys, ipod) So she changed back to her old self and me and my other friends didnt hear from her for 3 months. And now all of a sudden she is asking about when she needs to buy a dress oh and her husband is in the wedding by the way. At every get together (weddings & parties) she always makes a scene and starts a fight with her husband and threatens to leave him, the past three weddings she has done this. Is it wrong if i ask this girl to either not be in the wedding or to play a different role in the wedding? When i had asked her to be in the wedding i thought she had changed and was no longer like this but she has returned to her old ways. Please help! what should i do? this is a major stresser for me.
