What’s the chemical called that is released in the brain that gives one the feeling of being in love?

After a woman sleeps with a man, even a bad one, it is released into the brain….

I think that it takes almost two years to dissapate (sp?)…..

I thought it was oxycotin, but that’s a drug, lol.

What’s it’s name?
Chez- Thank you very much for that dopamine and oxytocin (not oxycotin).

Now if someone could please tell me how long it takes to be completely inaffective, after a relationship has ended I would appreciate it. After there has been no touch between either parties for a long period of time, how long does it take the body to catch up with the brain?! (I’ve heard that it’s usually two years for women and I want to know if I can hurry that along)

Thanks
