Advice please! Rejection!!

Ares

I got rejected last night for the first time. I’ve never been rejected by a guy before so it kinda blindsided me and physically I had a fight or flight response thing that happened. It stung a lot and my ego was deflated and my self confidence was crushed not gonna lie. I know I sound cocky and maybe I am but I dont know how to deal with rejection cause I’m not used to it. The worst part is the guy I wanted to have sex with has had sex with me multiple times. So it made me insecure that maybe he found something about me physically he thinks is ugly or gross idk. We weren’t anything serious just fwb. Any advice on how to move past the rejection?

Ps: I’m also a little pissed cause I moved to the Deep South where no one practices basic hygiene or gets tested or educated on sex so it took me close to two years to find someone that I trusted enough to have sex with.
