It is not ok for you to be treated this way by your WW. It isn't no matter what you think your failings are.
You have been hurt and as a modest shy man that hits at self esteem. Truly it does. You seem to me to be an ordinary H, with ordinary needs and requiring a faithful W.
WW could have taken a different course, could have resolved some issues with you. All sorts of choices. Her behaviour was her choice and is her responsibility.
It is rotten and you deserve better.
I always think that when an LBS is as down as you are then there is likely some trauma behind it. A reason, a source for those feelings and thoughts, some compounded damage, possibly from childhood. Before you go digging deeply into the changes to make, I suggest some extreme self care, some tenderness, some compassion for yourself. I want to say, ok you had some choices, possibly some poor ones. You didn't cheat or lie or treat your WW with disrespect as she treated you. I want to say this is not ok. I want to say that survival is important that you are important. That what you think and feel is important. I want to say that I believe you and am sending you some strength for today, for those moments when it's unbearable.
I want to say those things to you, so I am saying them. I am saying it's ok to go at your own pace and feel what you feel.
Hugs
