Cadence, I'm sorry you are feeling low and pushed into a place you would rather not be. However, you haven't been left much of a choice. The way in which he has distanced and separated himself and refused to work this out amicably is just cruel. With any luck his lawyer will see that this is going to be messy (read expensive) and suggest a resolution that gets everyone out as quickly as possible.
In the meantime, do focus on you and good times and try to keep this in the back of your mind. Legal processes are very slow and if you try to ride the tide of this it will make you seasick.
