I love him but I can't hide the fact that his girlfriend is still existing. I am so confused about his feelings for me, if is it really love or lust?

You always want what you can't have. He is an ex boyfriend (and you are an ex girlfriend) for a reason. Move on with your life. If you try to damage his relationship with his current girlfriend then karma will seek out remittance later on from you.

I say you are in love with being in love. If he was single... you probably wouldn't want him as much because his social worth is low since he doesn't piqué the interest of another woman

I'm confused too.
How can he be your boyfriend if " he's already taken?

It's not love OR lust, it's an obsession. You need to redirect your thinking. Whenever you think of him you need to think "He's not available" Then give yourself something else to do. Move on. Don't spend time wanting something you can't have.

Good luck.

Doesn't matter if its love, or lust. If he has a girlfriend, its unhealthy, and unwise, and is lying and cheating, so its WRONG.

So stop helping him be a lying cheater and totally wrong.
