Have sex with him or tell him to, well... beat it, for lack of a better term.
Maybe Its Love ;)
prove him wrong about what he is thinking
She was enamoured of her boyfriend as she could not stop thinking about him.
Stop having sex for sometime and see if he is paying attention to you
find a new boyfriend or girlfriend to stop you thinking about them ( your ex )
the reason you cant stop thinking about your boyfriend is because love does that to people. you love people so you think about them when your not around them!! that's just how it works! its great, don't u think? love is a very strong word and it has that effect on people! <3
he is probably wanting to get back together.
He's probably thinking about breaking up with you or it's a hint for you to break up with him.
just say i dont have one because i have a boyfriend or say i know what i am talking about.
Stop thinking about girls and get them into other things like books or somthing
this is not a problem. he should be happy. this is a good thing.
have some fun with your friends.. yes, its not easy.. but in just a little time, you could not think of your boyfriend because you had fun laughing and chatting with your friends..
