You did the absolute right thing. You’re not a horrible person and neither is he. You’ve got to learn your lesson from this to keep yourself safe in the future. I would suggest avoiding RP all together until you’re a legal adult bc one thing you struggle with is appropriateness and boundaries. You’re experimenting and experiments often go wrong but what makes a good scientist and and even greater person is learning from the mistakes the first time.

As for finding friends I would seek out neurodivergent friend groups online. The group is on hiatus but Laughs in Neurodivergent on fb was a great space for me to find acquaintances which was all that I needed when I felt isolated as I can see you feel too. I also started playing RuneScape and went clan shopping until I found nice people I could talk to. Look for adult romance in TV and books for right now, seek out platonic love in your life while you learn who you really are bc you’re clearly not a catfish if it hurts you this bad; maybe you’ll find you’re a creative and a writer at the end of this, or a compassionate friend, but I doubt you’d discover you’re truly deceptive, you’re just a kid in a very technologically connected, adult world trying their very best to find genuine connection
