Most Helpful Guy
Most Helpful Girl
Realize that he is not a respectful or honest person. Is that someone you really admire or respect? He doesn't respect his relationship, and so he wouldn't respect yours if you dated. If he truly valued you, he wouldn't flirt whilst remaining with his girlfriend, he would end things with her, so he could pursue you. He's playing with you, manipulating you, and you have to use your intellect and realize that you can make better choices than to settle for that.
