MelissaAnn, my heart goes out to you, nothing to be sorry for either. You should be able to come out on your own terms and the time that is right. What she is doing with your sons and family is very inappropriate. Like you said, it appears she is grasping at straws to beat you down and make herself feel better, to try and put some big event over the whole being married to you things because she finds it embarrassing or whatever.
I am in somewhat of a similar situation, although I have two tween-age daughters and am still married for the moment, it's in the early stages of ending. My wife is far outer edges of being non-supportive and up accepting, to the point she's threatened public posting on Facebook, direct outing to friends and other sports parents of our kids, all the name calling and derogatory terms a person can think of, and more. It's no fun to say the least.
I wish you the best with you ex, your children and your family who all of sudden seems to want to be back in your life. Keeps us updated dear!
