It's good that you are aware enough of what he is looking for from you and are able to ignore his calls. And marriage is a two-way street, this is in no way your fault, he needs to own his mistakes. Not make you own his mistakes.
Maybe school will be a good distraction for you from all the stress your H is giving to you. Just focus on your classes and not your H.

It's perfectly natural to feel that way. Ask anyone on the boards and you'll see they all went through their own personal hell. It's something that you're going to learn to cope with on your own.
It's good that you're seeing a C. Keep yourself busy and occupied with things that will get your mind off of him. It's not going to happen overnight and you're going to feel the pain gnawing away at you every day. But eventually, the pain gets less and you start living for YOU and not for HIM.
Stay strong.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
