1 year into trp. 19 yo

Me and my fwb are in the same school, I get jealous and angry when I see her talking to other guys. I manage to hide the butthurt but oh man I produce a thousand scenarios in my head, because Ive lost all trust for women. What should I do? What can I do?

I dont think Im perceived as a beta because she developed interests similiar to mine hobby-wise. She is pushing for commitment as well. I receive blowjobs in alleys and in other people’s apartments’ halls, roofs etc. I literally guide her to my dick every time we’re outside. Never pay for shit etc.
