Too soon to look backwards, T. You don't have any perspective yet. Get through this first and then look backwards.
When I called the DB coach he told me that I had neglected my H and that was why he cheated. I'm super curious who was supposed to be taking care of me? I was in a serious depression and highly isolated at the time when I was supposedly neglecting him. But I think he has to show up in order for me to neglect him, and I assure you, he was physically NOT THERE. Anybody who can tell you what was going on in your marriage is just reading tea leaves. They have a tiny little view into a tiny fraction of the thousands of moments and feelings that make up a marriage. You'll sort all this out when the time comes, but now is not that time.
Don't worry about what H is doing. Good for you for taking space, etc. Keep clearing your head and don't look backwards yet. There'll be time for that when the dust settles.
