I don't know anyone as oblivous as I am to the female race, case and point the story below.

Girl and I been hanging out for a couple of months, 95% of the time with certain friend or at least with other people. My mate and I both met the chick at the same time, and the 3 of us just end up hanging out alot as a little group. I am attracted to her, which increases each time we hang out as we seem to have more & more in common, but due to a previous love triangle I was in, I'm hesitant to make a move and ruin the friendship. On a Friday, ask her what she is up to that night, she replies with nothing so I ask if she wants to go to dinner. She accepts, "what about [friend]?" I say I will see if he is available, he isn't. The 2 of us go to dinner and then head back to hers and watch some tele (pretty common). I'm pretty knackered from work and am just talking jibberish and no longer thinking straight. We share a blanket on the sofa, and continue to talk for a while. She points out that I'm so drowsy that I'm in no state to drive home, I think I said something like "I'll sleep on the sofa", but she convinces me it's too cold and to get into her bed with her. I do. We continue to talk for a bit, I'm still just rambling nonsense. She tells me that I won't be able to sleep with my jeans on that I'll be too uncomfortable. She says "If you take off your pants, I'll take off mine", After a bit, I take the jeans off, she doesn't take off her pants. After not too long I fall asleep. Now if you're any normal person, you're reading this going "WTF are you thinking man."

I remember thinking to myself after getting into her bed... "she has called you 'gay' a couple of times, referring to how much of a nice guy you are, what if she really thinks you are gay, and you are like her gay friend where she trusts you that much to get into bed together." She tried to take me out of the friendzone, I was held on for dear life. Only dawns on me the next day with all the signals, oh and the fact that she has a spare room with a spare bed which she never offered that night.

TLDR : Get into bed with girl I have crush on, friendzone myself and don't make a move.
