Should I divorce or not?

Here is my problem. I've been married for 3 years. When we were dating verything was great but we started to fight inthe very first day of our marriage and it went like that. Now we dont even argue, not that we are getting along well, we just dont talk each other so often. The biggst problem is we dont have , we have but rarely, may be once a month and only once. Also he doesnt take care of his personal hygene, he takes shower once, may be twice a week. He has a bad breadth problem and that makes everything worse. And always I am the one who seduces him to have . We dont have a child and so far I realized that I dont want to have a child from him. I dont know, he is a good man but being good is enough to survive a marriage. Please advice me something.
