alright im gonna tell it like it is. Maybe the guy actually feels like he loves you, but chances are he just likes you a lot. If you don't feel the same, then theres nothing you can do, and the longer you're with him, the harder its gonna be on him when you decide you like one of the other guys your dating better.
which leads me to my next point. Its never happened to me, but if i found out the girl i was dating, was dating other people, I'd tell her to go fuck herself that dumb tramp, and leave for good. fuck that! I'm all about playing the field, but if theres someone I wanna date, I dont think its cool at all that i date other people at the same time. This isn't the 5th wheel or the Bachelorette where you start off with 18 guys and work down to one... just find one you like and stick with it. It'll turn into one hell of a better relationship that way.
