Arguing in a relationship?

I am in a similar situation where everything about the guy I'm with just seems to irritate the heck out of me. My opinion is that although you do love him, maybe you realize that you are in a relationship with someone and accepting some of his ways when you knew thats not what you wanted in the first place (the smoking, tattoo). You might just find yourself dealing with him because you feel that you have to. Maybe you dont really like this guy any more because he may not be what you want.
