30M starting to give up

I'm 30 years old, and I have not had a girlfriend in six years. I met a girl w few months ago and even went out on a date with her and hung out at her place a couple times. But she apparently decided she didn't want to date me and stopped talking to me. I have been trying dating apps like everyone else. I either get no matches or the ones I match with are bots/scammers/OF models/prostitutes. I'm so close to just giving up and accepting that I will be alone forever and I will never lose my virginity. I actually get along with people really well for the most part and have quite a few close female friends but I can never get beyond the friend stage. I'm taking care of my mental health and I'm mostly pretty responsible and quite emotionally intelligent. I genuinely don't understand what I'm doing wrong where I can't meet a woman that I want to spend the rest of my life with. I refuse to wallow in self pity but being lonely all the time really fucking sucks. Any advice would be helpful.
