Love or lust? how to make him want me

e orot lust?I'm seeing him for the past 2 1/2 years and we have these huge fights and its all because of me-I'm needy. But my parents got into a nasty divorce. So I started to practically live at his house. He only started to change when he started partying. And he stopped flirting with any and flirted with every other girl. He broke up with any and said he missed me and I missed him. But how do I bring that spark back?

also how do I keep from having sex? I want love not lust
