It sucks with a capital S. Call me if you get stuck--still have the number? I ended up doing 95% of the work for the D since I was the one in the house. I would have gone with a mediator, given the choice, but he felt he needed representation, so I had to get my own L. Going through the collaborative process (so motions don't have to be filed all the time) right now.
If MA is no fault, you will get at least 50% of available income and assets. If it is fault state, it might be more with evidence (but not many places do that anymore).
