Yooo my dude. That’s some fucked up shit. I kinda been in that situation myself, I had started developing feels for a slutty girl. I knew she wasn’t a keeper, but shit she was hot AF and great to talk to. What I did was fucced her a few times, then constantly reminding myself that she isn’t to be trusted. Soon, she made herself a boyfriend, then another one then another one etc etc. I’d stay I don’t regret it. My advice, Think about her and if she is trustworthy. She probably isn’t, so please my guy, don’t dump your girl for a hoe(unless you have problems urself with your gf). Whatever you do, never open up to that bitcc, do what u gotta do, but dont put ur soul in it.
Peace
