Wanting to go to Posty Fest but bf says rap concerts aren't safe.

Wanting to vent. He said that I could get raped and stuff & that rap concerts are crazy. He said he would want to go with me even though he doesn't care for Post Malone's music. He's more into screamo & devilish music that I can't stand. I can't afford to go but I would love to be able to go with a best friend. He still said that would be stupid for me to go without him in case something happened. I'm 24. He's 26. I'm not a little girl. He's treating me like one. He's controlling. I mean yeah I get what he means about it possibly not being safe especially since there has been concerts that have had mass shootings unfortunately. Surely they have taken more safety protocols since then though. Last time I went to a concert was a Britney Spears one which was years ago when I was younger. I would love to be able to go to a concert again and have fun. We have a 3yr old daughter. I can not remember the last time I got to do something fun that I like to do. I need time for myself. I probably won't get to go unfortunately. I am bummed out. I have a celeb crush on Post so it really sucks to not get to go see him perform.
