You want to attract this specific person, go and attract this specific person! This is what your heart tells you to do now, so do it, don't doubt whether you can, don't doubt whether he is the one.
If you can not think of someone better for you at this moment, then there is no one better for you at this moment.
And maybe, just maybe, someday, someone else comes along who changes the game completely. It happened to me. I could not imagine anyone else, have even been with another guy and still thinking of my POI...through PW we became best friends, are closer now then we ever were before, but I still wanted more...until I looked K. in the eye...lightning struck....and my whole believe of 'the one' just tumbled upside down.
Maybe there is another guy out there who will make you forget your current POI. Then you won't care whether you attracted him back or not. Maybe there is no other out there for you. Then you will have him back. Either way, you will be completely and doubtlessly happy.
