I don't care whatever the cause, booze, depression, etc. The fact that he has been physically, verbally and emotionally abusive with you and you are trying to rationalize it is troubling. No woman should have to put up with that and it usually escalates. It isn't about his disease, it is about the fact that he abuses you. Period. Please don't rationalize it think it will change. It may or may not but the point is he is that way NOW and you need to get out. Emotional and verbal abuse is still abuse and just as damaging. Are you in any type of therapy? Have you ever considred looking into a woman's group? support group for example?
