Jen, just read my posts! We are here to help. Go back to your old resources and maybe they can help you. DO you want him to leave again? If so do it, that is your home right? If he is making it bad make him leave. Be strong and make some calls today. Try and be the Mom you want to be, if he is not going to be the husband he needs to be why should you try to be a good wife. Consintrate on what is good for you and the kids.
After all the crap, is it better without him? I mean when he was gone were YOU better?
