I think that you handled the C about as well as you could. I'm glad to hear that you'll be going back. That will be more important that you know. As things progress legally, you will definitely want a C to discuss things with.
Just a tip- Your W is not getting a full time job because that will hurt her chance of getting the max amount of $ from you. I'm quite certain her L has told her that. That's also why she's going for primary custody.
The house buy out option sounds like a great option for you. Do not discuss this with your W but do talk to your L about it. It's not about revenge or getting back at her. When you think about it, this is best for her as well. You're buying her out = she has more money. She probably won't see it that way at first but she might later.
All in all. You're doing better. Hang in there and remember she's not your friend right now.
