Do not quit your job!!! I know you think this is a 180, but this is a very dangerous decision. If this does end in divorce, you don't want to be faced with a situation where you have to get a job quickly. Also, any lawyer will tell you not to make those kinds of changes right now. It will look very bad if you go before a judge and say, well I trusted him to take care of us even though he had moved out and asked for a divorce.
Although it is very important to make changes, you have to think about what is best for you and your child.
Good Luck with parents! My husbands parents came to visit twice since the bomb. Both times it was very weird. Don't engage them in conversation about your sitch. It will only end badly, and if you do reconcile you don't want thing to be awkward.
