The silent treatment is emotional abuse.
Being angry because your wife isn't in the mood,and having a tantrum about it is an attempt at coercion.
The fact that you are unwell, and he is choosing to act this way, rather than be loving,concerned, and understanding is abuse.
Infidelity is abuse.
Sounds like he's an abuser.
I'm sorry you're unwell. I'm dealing with health issues myself. I am in pain, and going through numerous tests to determine what's going on. We haven't had sex in almost 3 months. My wh has made a few comments, here and there,about how if I was feeling better, he'd like to..but he hasn't been pushy,or moody. If he was, it would make me feel so much worse. And I don't know if I even want to attempt reconciliation again. I'm leaning towards not. But,that's not even something I'm thinking about,until my health is better.
You deserve better. It's ok to not want sex when you are unwell. Your wh needs to grow up. And,honestly, if this is how he is treating you now..as we all get older..many people develop health issues. Can you count on him to take care of you,if you need it? Will he be empathetic, and loving. It doesn't appear so. That is something you need to consider.
