I’m Uncomfortable With My GF Being Friends With Her Ex

I posted the screenshots to this note I wrote because I didn’t think it would all fit.

I really just need advice on this because it’s bothering me so much. Also, please don’t be rude. I just want unbiased opinions since I can’t speak to anyone in my personal life about it. I just want to figure out how to work it through it, if it’s possible.

Edit**

I officially ended things for good last night. She says she’s grown and can talk to whoever she wants to talk to, which of course she can. But I don’t have to deal with it. I told her I felt like second best when her ex is in the picture and I deserve to be with someone who puts me first.
