GoodKarma, I do sympathize with you, really. I know it's extremely difficult... love and family often are... but they are worth it. Focus on why you are doing it. You are doing it for him and he is worth it. Just try your best to be nice and supportive. Try to remember the things (if any) that you liked about her before and focus on that. If your family is supportive, who knows, you may make the difference in their marraige. She may truly be sorry and change... eventually making it easier for you to genuinely like her again. Let's face it, we all make mistakes, some bigger than others. She may not change and he will need you then as well. Just support him... that's what you would want from him. What you need to keep in mind is that if all of you are angry and it's obvious that you still resent her and don't support him... that is negative and all of you will be miserable. No good can come from that negativity. If you try your hardest to support him, and you are pleasant to both of them, maybe you can share some positive, happy memories while he is going through this transition. All of you need to get together and decide that he is worth the discomfort of being nice to her... that you are going to have treasured family time that won't be interrupted by her destructive decision. You are a family... it's worth it. - Hang in there!
