Can I save my marriage?

[Lll54]

I just read this and sound very needy. But I don't think I am. Many people live in the same house but different bedrooms, but are actively working on their marriage. I don't know what we are doing! Like I said I don't want a room mate. If he does not want to fix this marriage, then he has to leave. I can't be just "friends" with my husband all while "living" with him. My children and I deserve some stability and security and right now we have none. He has made no attempt to say anything about our R. I'm not going to be his doormat.
