Technically yes. My ex cheated on me and I didn't leave, spent six months crying myself to sleep etc. One night he started yelling at me, said he was done pretending to care and dropped me home. I didn't hear from him for three days, took it as a break up and went and slept with someone else. He was just giving me space and hadn't ended the relationship. Other than that mess, nope! I'd honestly just leave if I felt the need that badly to be with someone else.

Nope. That's really disrespectful and against my morals

No and never will I think that is super disrespectful and I can't stand it . If you are with a person you are supposed to give them loyalty and trust if not then why are you with them . I hate how people can just damage someone's emotions like that.
