Is it normal to want a guys that has a gf?

Just do him. simple.

Do I think this is right?

No.

Do I think this is normal?

Absolutely.

When a woman is with a man, she's a saint. When a woman isn't with a man, she's a homewrecker.

Such is life.

I think what you're experiencing is that you are "smelling" him. See, I know that is gonna sound stupid, but when we are sexually active, or with someone of the other sex (as this guy is with his gf), we, (as humans and like animals in heat) give off pheromones (scent) and you may be experiencing that. Think about it this way: If you had a good friend or a daughter, what would you tell her to do? Stay or leave? Take a step back and analyze the situation that way. This guy wants to play with you, don't be his toy...

i sorta have the same situation. well the bloke isn't mean to me. we've actually been friends for a while, and i've liked him for a while, but he has a gf. i have nothing against her though, we've talked before and she's pretty nice, so i don't want to jack him away from her. but i'm beginning to think he knows i like him, because sometimes he'll talk to me but sometimes when i say hi he'll look like he's trying to ignore me :/ idk.

You ask what to do?

First you have to decide:

Do I want a Fk-buddy or a boyfriend?
Since this guy is too mean for bf material then
the choice boils down to Fk-bud OR nothing.

Def leave but it is wicked hard

Leave. The sooner the better, for your own sake.

So you want to be a home wrecker? What goes around comes around

Holy hell you are an idiot

It's normal to fall for someone even when they are in a relationship, but you should probably leave. You don't want to be the other woman that suduced him, it will make you feel bad and nit able to trust him. If he wants you he will end it and find you.

Leave

Ask for a threesome.
