How to not be so obsessed with my boyfriend?

ok so im 17 and i have had over 15 boyfriends over the past 2 yrs. They were all short and didnt last long and all were full of nasty guys that were trying to use me. Till one day i met this guy who begged me to go out with him so i said ok even though i was still getting over my last bf who kinda of abused me by hitting me when he got super mad. So me n my new bf dated and it was kind of rocky at first cuz we really didnt click or open up with each other..until i tried hard to forget my old ways and we learned everything about each other and got close and hes so wonderful and he bought me dinner a necklace etc (no other guy did ever) and he introduced me to his mom and i was(am) able to go to his house whenever i want and he cuddles with me and treats me right and then i was a virgin and he NEVER asked for sex (which was different from all my other relationships which thats all they asked for but didnt get it) then after 3 months dating him i lost my virginity too him. And now this is our 6th month dating and i love him so much hes so great and more than i could of ever asked for. But im so obsessed with him and whenever im not with him hes in my mind all the time driving me crazy i wish i could stop. Ive never been this way before and i cant control it..i wake up early and cant go back to bed cuz hes on my mind..and i do everything he says now because hes just too amazing and i dont want to lose him. But how can i stop thinking about him so much?:/
