I want out.

I have been falling out of love with my husband. It's getting worse by the day. I can't take his tone of voice anymore. I can never tell that he's playing around. I've secretly been crying in my bathroom. It's emotional & financial. He likes to pick & choose when he goes to work. Last week was his first full week of work & that's bc my new SECOND job is near his job. Every check if his gets taken for child support. So when he decides to only work 11 hours one week... That brings home around $14 to contribute. I'm losing my mind. My previous second job I had was nights working every weekend plus a day job the beginning of the week. I left for almost a year in 2014 for a divorce if he couldn't change. We married 2013. I'm unhappy. He knows how to turn things around on me to make me feel crazy. Nothing's going to ever change if it hasn't yet. Advice?
