How can I get him to choose me over pot?

Me and my boyfriend dated for 7 months. He smoked pot in the beginning and I told him I wouldn't be with a person who does that. He said he always told himself he would stop for the girl he was going to marry so he quit. We started fighting and he started smoking pot behind my back around the 6th month together. We broke up for 2 months without speaking and now we are trying to work things out. He still smokes pot.. and I told him it does not bother me as long as he quits when its important and time to. I just don't know how to make him fall in love with me again and to stop smoking pot without me nagging him and bugging him.. I also want him to be nice and treat me right, I feel like I'm the only one really trying to work things out, but he agreed to this.
HELP! how can I make him fall in love with me again?

I know its so hard. but I mean if he TRULY TRULT LOVES YOU, he would stop if he knew that it was makijng his girl feel miserable through out the day and be the last thing on her mind at night. my advice for you...if he doesnt love you, what can you do, you know> sometimes it takes guys a while to realize that theyve lost something good but for now theres not much to do. I hope this helps

Uhhhh....why do you want a pot head who lies to you to love you?
