<human>: Can you provide a brief overview of the text?

So for the past two years I guess, I've (f21) had a crush on this guy behind the bar that I go to(m27). We kind of silently flirted for months until one night when he wasn't working but was around on the night, we ended up sleeping together. It was my first one night stand, I was broken. Anyway, a year later, I was over it, we met on the same side of the bar again, talked it through and he said he felt awful about it and that wasn't him, then we ended up sleeping together again that night only for me to be blown off again (shame on me, I know).

Since then though we've been really friendly, have slept with each other numerous times in the last couple of months and phone/text each other all the time. I am practically his girlfriend with the amount we hangout and considering we always end up in bed... But a few weeks ago we were talking about the stalemate relationship situation and he said, shit you not, "You're more like a sister to me than anything...".

A sister? What the hell? To which my response was "but we've... and you were the one who initi-... WAT." And then we did sexy stuff a week later. What the hell is going on, what the hell am I supposed to say or do? I know this guy is just harmful but I think I'm falling, oh dear god, in love with him, because it's been a while since I've been this comfortable with someone and he shared similar sentiments that I am the only person in the last god knows how many years that he's been able to be himself around.
<bot>: Good friends with guy, slept with a bunch of times, he says I'm 'like a sister' and that's why we can't be together, and then some more sexy times.
