I have been in a similar situation where I was not happy at all with my husband. I was going to school, full time and working full time. I supported us. We stopped communicating and it killed me. as soon as we both talked and shared how we felt with each other, things got better. I thought I was done with him too. If you have no communication, you have no relationship. I don't know if this helps but try writing him a letter. That is what I did and lots of tears later, we are still together and happier then we ahve ever been. It does take time and you both have to be willing to listen. If you are not it anymore it is not fair to him to keep trying at something that is not there. As far as the single mother thing goes, maybe you can find some finacial help or a well-far program to help you out if you do take that route. Good luck!
