My Husband Is Not The Man I Married...Help?

I have been married for almost three years. I have no children, but I am desperately in love with my husband. I have no idea what happened, and I am sure I am at fault somewhere. My husband used to be so doting, he would do everything and anything to make me happy, yet over the past year he won't let me come around his friends (he says I create too much drama—so if he goes to hang out with any of his friends I am not allowed to come...tonight he's going to a cookout), he started calling me names, he gets overly frustrated with me all the time and says I annoy him. He says he loves me sometimes...I asked him if he was seeing anyone else, he just avoids the question…actually any question that involves our relationship on any real level. He will spend money doing stuff with his friends, but never has enough money to take me out on dates. We just stay home, eat, watch television, or take naps together. He hates my parents suddenly enough to avoid going to my family functions, but gets really angry if I don't go to his. I cook for him all the time, I clean up after him. If I do anything wrong by his standards he yells at me. He almost never says sorry for hurting my feelings or being mean to me. I say sorry all the time...too much I gather because now he won't accept my apologies. He says sorry coming from me doesn't mean anything anymore. He doesn't trust me at all. He checks up on me all the time, won't let me wear clothing he deems too revealing, and accuses me constantly of cheating on him. Having relationships with other men is out of the question, and it’s even gotten so bad that he has started saying all my friends are bad influences on me and gets angry if I do anything with them. The bedroom has never been an issue for us. I have always said that this is the only area of our relationship that has never suffered any issue. He is attentive and loving. I just don’t understand why it doesn’t translate to our “functional/practical” lives. I don’t feel wanted, loved, or needed in our practical life…I just feel like a bother all the time. Emotionally I am so frustrated and exhausted because it seems as if everything I do doesn't help…sometimes I feel my efforts just make things worse. He tells me I should know what I need to do to make this relationship better. BUT I DON’T!!! Does anyone have any advice for me? I wanted to take him to counseling but he refuses to go. I don’t believe in divorce unless it is the last resort…I don’t feel we’ve gotten there yet. I want him to love me again, to treat me sweetly and kindly. The man I know today is not the man I married. Is it too late? Can I do something to change his attitude towards me? Please, anyone…Help.
