You are still young and you are going to be alright. Just make sure that you concentrate on whats important. I would try to work it out with the husband, but remember that if he doesn't want to stay you can't force him to stay. Take care of yourself and your babies and I think it's a good idea to go back to school. I am 34 years old and I am a single parent of one. It was hard with my one so know that it's not going to be easy but also know that where there is a will there is a way. You are well on your way with the weight loss. Just think how great you are going to look wants you get it under control. Good Luck!
