Ok, to make a very long story short...

My best friend "Jeff" is straight. We have known each other for 3 years. Were complete opposites but for some reason we just click. About 2 years ago, we fooled around a couple times until someone at work found out about us and "jeff" couldnt handle the pressure and we stopped talking for a while. "Jeff" then decided he desperately wanted a girlfriend, and eventually picked the first girl who showed any interest in him. They were together for about 8 months and then broke up. Since the fiasco at work, me and "Jeff" have had a rocky and very difficult relationship, until recently. Now we are exactly like we were when we were folling around...Were always together, we act like a married couple...he does the things that he knows turns me on...but this is the guy who beats you over the head with the fact that hes straight. Ive called him out on this before, that he does and says things that make it sound like he wants to be with a guy (me) but then likes to walk around and talk about how much he likes girls...So im confused...Should i continue to spurn his advances because maybe he doesnt have it in him to say he wants me...or should i give in and see where it takes me although i might end up getting hurt again?
