Watch a few showing of Cheaters on TV, see if that won't help to get your mine set in what youíre dealing with.
I know for a fact everyone is subject to cheat. Men or women.
Given the right situation it would happen and anyone saying thatís not so is not being truthful.
Now having said that there are many people that will live happy without that situation ever coming up. But given the right girl or guy they would be all over it.
You might be better off to move on and stop being played. If you treated her wrong learn from it an move on. Good luck.
