Wtf is going on with my guy freind?

Right long story short. Got a guy friend, pretty close with an emotional connection, there is a vibe but our love for each other was decided to stay platonic. I excepted this, but now he's constantly bring up the subject of sex would ruin us. Why the fudge is he continuing to say this and go on about how much he loves me when a decision has already been made on this subject? (usally after some drinks.) It's kinda getting anoying.
