You handled everything PERFECTLY!! Along with your new level of detachment and GAL I know that you will be fine! And don't be surprised when your husband comes to the realization that his "soul mate/OW" isn't the life that he wants. I have a STRONG feeling that this new visitation arrangement and you cutting off the emotional needs that he gets from you (happy, calm, dependable) will be a RUDE awakening for him...If he is smart :-)
Hugs to you newmama!
