If you two have been broken up for a while, one of the things you're going to have to do if you want to get him back is get on his mind again.
  Somehow, you have to start the wheels turning in his head that make him think about how great being back together could be...
but how? There are several ways to do this, and a lot of them are simple but not really what you'd call "easy.
"  Things like looking your best all the time and appearing to be happy without him can spark up a little jealousy, but they're not really "it" for getting him back.
There is ONE way though, that's guaranteed to get him thinking about you, and will actually end up getting him on the phone talking to you (which is always a good thing if you're trying to get him back!).
It has to do with striking at his interest and making him genuinely curious about you, via a somewhat cryptic phone call.
  This is the same thing I recommend to people who are just trying to get their exes to return their calls, but it also works wonders for getting you on his mind.
  Try making a call like this: "Hey John, it's Susan...
I just wanted to thank you for what you did, it really helped me out.
  I'd like it if you could call me back, because I'd like to thank you in person.
" I guarantee a call like that will not only get him seriously thinking about you, it'll get him on the phone quicker than you'd ever imagine.
  It appeals to his self-interest and curiosity, and he'll be unable to help but see what it was he "did.
"  But be careful, not having the right follow-up plan for when he calls back will easily make this backfire, so check out the link below before you do this.
