I'm tired of this..

I'm tired of missing him.. And I feel like the only way to get over this guy that I love is to find someone better... But every time I find a guy he wants me for sex. And everytime I get a nice guy that don't compare to the man I love... I miss him. And he is to blind to see that I love him. I have been searching everywhere... And I can't find mr. Right all I seem to find are all the wrong guys. I hate this.. And I am tired of going to do something sexual with a person when I'm the middle of it I am like "stop... I can't do this.." Because it doesn't feel right with a different guy... I need help.
