I'm glad my post didn't offend you. I was a single mom, too. I know how hard it is even though I wasn't divorcing an alcoholic, I was divorcing an azzhole control freak who wanted to hurt me more than he cared about his daughter. Anyway, I know how much you want to be free from your husband and I felt the same way. I'd have done anything, even if it meant taking a job I would just tolerate if it meant the money I needed. I took a lot of those jobs, but now, I'm working in a job I love, doing what I love to do.
Take the weekend to think about it. Maybe something will come about with the job you really want that will be encouraging about it becoming full time. That would be the ideal, wouldn't it?
