Marriage troubles

I've been having a real hard time, feeling attracted towards my husband. We've been married for 1 1/2 years now. This feeling had started before we got married. I just thought it was the infamous "cold feet" but nothing has changed. I talked to him about it a while back and chose to stay and put a major effort into improving our relationship. Presently, I feel even less attracted to him and emotionally shut off from him. I'm going to give it another six months of trying to figure out if this feeling of hopelessness can change. Has anyone else been in a situation like this? If so, what did u do and how did it work out for u?
