Make sure to restate your point - you don't want this separation agreement or a divorce. You want to work hard on self improvement as he does the same. You did not want him to move out.
Remind him.
Consider telling him that you weren't ready for MC a month ago, but when you got ready he asked for the agreement and said it was hopeless.
Then, tell him he's asked for a legal agreement by law. You are willing to review legal issues. Blame the lawyer, not him or you.
If he makes a point, reconsider what your L said. This is your life to live, not theirs. The L will walk away happy if you get lots of money. Your H might be seeing this as, 'you're an adult....why do I have to pay anything?' and to some extent, a court may agree.
Agreements are agreements, if he agrees, it becomes law. That doesn't make it the right thing to do before God.
