Here's what I know...
(1) You need to take time to be in a relationship and make it work.
(2) If you want to be in a relationship, you will be willing to give up a trolling night to be with a girl you like.
(3) If a guy is not willing to give up the trolling night, chances are, he is not into you enough to forego it.
(4) A guy might say that he trolls parties because he really wants to meet someone but there is a difference between hitting the occasional party and going to the opening of an envelope!
(5) Some guys troll for sport and because it's a game to them and others troll because they think it is a necessity. Either way, do you really want to be with that guy?
(6) You have been in situations before where when a guy is crazy about you, he drops everything and can't get enough of you. If the trolling guy can't do this, it's time for another guy.
