Based on what trauma you have experienced I dont understand how you would even want to be intimate with him let alone care about how he feels being rejected. You have every right to feel sick to your stomach at the very thought of being "physical" with him. He is a selfish pig right now and needs to be woken up before he looses you and his family.
You really need to focus on what's important right now. And him being physically satisfied should not be on the top of your list.
The fact that you feel OBLIGATED to please him is a major part of why you are in this mess.
Once again just because 2 people are married does not mean the other person GIVES UP their identity and VALUES to satisfy their partner. That is a very unhealthy, controling R and should not be tolerated.
Your partner should TRULY RESPECT your BOUNDARIES and LIMITATIONS.
Good luck w MC. Hold your ground and STICK to your BOUNDARIES.
