Sounds good to me. It doesn't sound rude or cold and yet you are not sounding like you are saying too much (IMHO). Since he seems to get angry very easily, I would try to be careful not to intentionally sound rude about the visitation. If his schedule suits your needs okay, then I would tell him that it is fine. But, be sure your Thanksgiving and any other holiday plans are worked into all of that. Both of you will have a tough time this year, and it is not going to be easy to give/take about the holidays. Be fair, but don't let him take advantage, either.

I am glad you explained more about the MC, etc. I am concerned about you fearing his anger. Have you discussed this with your IC? I hope you will make sure that his anger issues are well taken care of before any reconcilling is done or you will be walking on egg shells from then on. One thing about being S, you shouldn't have to be afraid of him! You should have to be at any time!

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
