If you going to read this, please, help me.

If anyone is going to read this, i need you're help. I have a relationship 7 months until now, but he has hurt me plenty of times in past. I love him a lot, and I care about him but i want to break up. And I don't know how to tell it to him because he loves me too but the difference is that he is in love with me but I'm not with him. And as Blair said at the middle of the 5th season to Chuck "I love you, but that does not mean that I'm in love with you." But i know that my boyfriend is not going to understand it. And I don't break up with him because i care about him, and he says that when we will break up, he will star smoke and drink...and i don't know. I'm to confusing. Please...SOMEONE HELP???
