Is AUTHOR wrong in the post ? POST : For some backstory, my GF and the dude she wants to hang out with, who we'll call Blake, used to talk to each other and were super close the summer of 2018. They would always hangout and were still in the talking phase. A couple months later, she's no longer interested in him and that's when me and here start to talk. My GF and Blake still know each other and see each other in person and wave to each other, but never really talk anymore. 


I've always been paranoid with Blake and my GF still talking in secret since she's always mentioning him and saying things about him on purpose to piss me off, but she also always promises that they stopped talking and never do anything anymore. 5 months later today, she comes up to me and asks me if over the summer while I'm gone, she can hangout with him since he was always nice to her and was a lot of fun. She's promising me that nothings going to happen between them and that they're just going to be walking around and hanging out outdoors. This is a big no from me, but she keeps begging me saying she won't do anything with him and that I should trust her. All of her friends are saying I should trust her, but all of my guy friends are saying to not let her hangout with him. 

Im super stumped at what to do. I told my GF to please not talk to him or hangout with him and that any other guy is fine since I can trust all of her other guy friends since I know them closely, but don't know Blake that closely. 

Maybe I'm being petty, but I really don't want her hanging out with her EX alone over the summer.
