Has girlfriend but still wants sex

My good tauras friend has a gf but still wants to have sex with me.

Months ago he would not want to be alone with me saying it is not appropriate since he has a gf.

He is with the same girl now, so why change of mind?

Why would he say it's inappropriate to be alone with you just because he has a gf? I have a gf and I'm constantly alone with other girls :/

he probably doesn't have much self control but now he probably decided to have sex with you anyways so it doesn't matter he was alone with you or not

Yes in May he did not want to be alone in a room with me, but now he is willing to book a hotel room so we can have sex. He is with the same gf as before, this baffles me.

While we were fooling around today in the car, I asked why he wants to do this with me, said he loves the chemistry ( we do have great chemistry, have always had), as much I want to have sex with him, I keep backing off because he has a gf. I don't like to sleep with a man if he is involved with someone, neither did I want to sleep with him before. I only wanted to see this place he bought, but he denied saying it is not appropriate b/c he has a gf. Puzzles me.

Maybe self control...but why now?
