Am I stuck in a rut?

I have been with my boyfriend for 3 years and have to say that I am starting to get quite bored with the relationship. He isn't a loving person, doesn't ever want to go out to the pub and would rather stay in and watch the television all of the time. Before I met him I was out every weekend clubbing, but because he doesn't like clubs he won't go out with me even though I go to watch things that he wants at the pictures and do things at the weekends that he wants to do rather than what I want to do and makes it difficult for me if I try and suggest new things. Two of my what I would call close friends have both said that I should finish it, but I love him so much and just don't know if we need to go see a counsellor, or I have to sit him down and tell him that i'm unhappy. Thing is he won't change, and it's almost like he hasn't got a backbone doesn't have an opinion and just keeps plodding on with his life and is bringing me down with him - help!
