Is he right for me?!

I have been seeing this guy on and off for 2 years now. We started out as friends. Now it just seems like we argue about every little thing. He has been saying he feels like we rushed into it and I feel like it's just because we have been arguing. There is built up tension between us because we don't talk things out. We argue then we go right back to just talking like nothing happened. I feel like we need to sit down and actually talk things out or could it be that we are just better off as friends. Keep in mind we love each other very much but I want what's best for the relationship. What do you think?
