I think, she does resent me leaving, and her behavior is linked to that. She wants to hurt me for leaving her-I dunno, I could be WAAAAAAYYY off base.
I don't know that you are. I know it doesn't make it feel any better, but it's something to consider.
So now would be a good time to think of 3 things that you wish were stronger or better in your marriage. Don't dwell on negatives like "I wish my wife would stop sleeping around"; think of positive changes, like "I want to be able to discuss our relationship more openly and honestly".
I know it seems crazy to think about working on the R in the state it's in. But it's more about knowing what you want for yourself and from your spouse in a healthy relationship.
