Have you ever cheated on someone you were in a relationship with? Similarly, have you been cheated on and if so, what did you do about it? Could you ever trust someone again if they cheated on you?
I have strong trust issues with men in general, and women too , except of course my best friend, I trust him with my life.
I have not been with someone since we broke with my ex, one, because of these trust issues, and second, because I don't think it's the most important thing. But if I discovered I was cheated on, my trust issues would be even more powerful ^^
