for some dumb a$$ reason I looked at her myspace, cause she is my top friend and her new name is new life = new adventures...her quote...moved on..
You already knew that, right? You found out about the A's that she has had. I'd take the next ten days to work on GALing and try to do whatever you can get to get on with your life. Yes, it's tough to deal with the realization that she has had A's before and during your marriage - Only time will heal those wounds, unfortunately.
I'd avoid contacting her unless it's really important and let her get over the anger that you have seen from her recently. Just remember - Now is not the time to try to figure out the whys and hows of the A's... She won't want to hear it.
