My boyfriend is a smoker. He says to me he wants to stop and I should try and help him. I mean how am I suppose to do that? I really hate that he smokes and all.

The only person that can help him smoke, is him. You can't do anything, and if you tried he'd likely end up resenting you.

Tell him to look into getting help to quit. That's the best you can do to help. Other then that, it's on him, and only him.
