I am sorry to hear about your situation. I have a good friend that is going through the same thing. Divorce sucks. Anyways, I think you both should come to some sort of compromise. Expecting him to pay support on an assumed salary of $155k is unrealistic. You don’t need a mortgage expert to understand the market isn’t what it was back in 2003. At the same time, he should sac-up and help you raise the child(ren) you both had together.

Educating yourself was a good move. You might consider increasing your attempts at building a strong network in your area. Try to befriend moms or dads in a similar situation. They might be able to help you through this transition phase while you get established in your new career (e.g., find a good, inexpensive day care). I wish you the best of luck.
