I think you would benefit seeing a Therapist to help you process the marriage and whether you want to stay in such a situation. Where does you Daughter receive her Therapy? Is there an option to go there ? If not there is county mental health services that offer sliding scale or even free sessions.

Its hard to make a decision whether to stay or go ... If he isnt willing to help improve your marriage then what you have is all your going to get . Dont you deserve more?. Life is too short to be unhappy or ignored

Take care
