First, welcome to PC. I am sorry that you are so alone and struggling. It sounds like an awful situation. Have you tried counseling? It sounds like he is not giving you the attention that you need to be in a relationship with him. If you are feeling alone like that, maybe when he gets home and you two have privacy, tell him how you feel. It would be worth your sanity and well being to be honest and tell him that you are not happy with this relationship. Maybe it will get him to think. We all need human interaction and not having family or friends near is not worth much. Depending upon how he reacts I would decide to myself whether or not I am staying and what my next step would be to help myself.

Best wishes.
