Replying to Trash cans being painted red to symbolize blood???

I figured that would get you to click. Okay, so heres the deal, my two friends, Abby and Tim have been messing around for several months, only Abby has a long distance boyfriend so he knew nothing. So finally Abby decides that she wants it to stop with him. Hes basically crushed blah blah. So somehow i get dragged into it and I've become wicked good friends with him,and hes over her and whatever. I am tryin to figure out if he has a thing for me or not.We talk on the phone every night for at least 2 hours. We don't really hang out alone, but I think we will soon. He also invited me to go to his family's campground thing memorial day weekend. We flirt occasionally, but it doesnt seem anything outrageous. He also talks about other girls to me. Whats his deal?
