How do you define infidelity (cheating)?
Having an affair?
Hooking up after a drunk night?
Paid sex with an escort/prostitute
Happy ending massage?
French kissing someone?
Staying active on a dating site?
Flirting?
Sexting?
All of the above.
It's not called controlling but I think a partner should be all about only you. Of course he/she can have friends, but nothing romantic with friends obviously.
My opinion😊😊
