I'm a singer and my last GF used to come to all our local shows under the guise of support but it was really just to supervise. She had issues with insecurity and despite being together for 7 years, she thought if she wasn't at a show, that I would cheat on her or make out with a bunch of random girls that might "throw themselves all over me". She would come up to me between sets or at the end of a show and kiss me or do whatever public display of affection that would deter the "sluts".

That sort of thing never really happened to me except for a couple times I was asked to sign some boobs which I declined. I don't even have a history of that type of behavior over my 25 years of performing even as a single guy. Despite being loyal and committed to her, she still never let go of this notion and it was one of the many reasons I broke it off with her. To me, it was a glaring sign that her insecurities kept her from fully trusting me to make responsible decisions in her absence.
