How to get over a fkboy one (2) night stand?

Anonymous
I slightly grew feelings for a fkboy that pursed me hard when I went overseas for vacation. I know it won’t turn into anything because he has so many red flags, younger than me and don’t have his shit together but the feeling of being with him was really nice.
I left and went back home, we texted a bit for a day or 2 and then he just stopped. I then find out he’s messaging my friend who has a boyfriend whom he met, and he knows she’s my best friend. Asking for her number because they live in the same city, totally weirded me out. He also isn’t watching my stories on social media either anymore.

I just need some hard truth and advice / how do I get back at him? I’ve started no contact to just detach from the communication.
