OH damn. I know just how you feel. My friend is engaged to this guy after knowing him for only three months. She’s completely infatuated with him and he’s all she ever talks about. Ask her how she is and she tells me he is. Trouble is, he’s got a rubbish reputation and I find it hard to understand how she believes him when he says he loves her. Our friendship is suffering too.
Do you have a legitimate reason for disliking him? Maybe you could see if you and her could just hang out alone and spend some girl time together to get your friendship back on track. If she really loves this guy though, there’s not a lot you can do about it.
