Have had similar experiences tbh. Gave it one last shot after I got my Master's. I had just restarted my career in a different field and moved into a new place. It seemed to jive with the newness I was experiencing at the time. Fell for this girl I worked with (idiot, idiot, idiot). She put off this pure, sweet, innocent, virtuous, Catholic girl vibe that I was really into (I was religionmaxxing at the time). It seemed she was the only girl I knew of who was both single and not an ugly landwhale, yet with whom I felt I had a realistic shot with. So yeah, I was tripping pretty bad for her.
Long story short, got brutally rejected and literally just a couple days after, found out she was not only fuck-buddying a co-worker I knew, but was camwhoring on the side. I was so pissed and embarrassed that I'd been so deceived and had made such an ass of myself. But then, more stuff came out about this girl's slutty past (completely ruining the reputation she built with literally everyone at our small company jfl, she quit two weeks later) and I finally accepted that all girls are sluts with whom I have no shot with. I threw in the towel, got into MGTOW and went though a few stages before eventual blackpilling.
The boyfriend assumption you mentioned can be pretty brutal too--had it happen to me once when flying by an older flight attendant by virtue of the coincidental fact I was seated alone with a young female in my row. At least the girl didn't say "ewwww", but she laughed and gave a sarcastic response back to the attendant, demonstrating there was no way in hell I was her boyfriend. Brutal.
Bro, I'm so sorry. Although I am young, I do not intend to try surgeries, it is most likely SEA, but I prefer to pay good quality prostitutes, I will never have the real love and pampering that I want from a woman anyway.
I know two guys who succeeded with SEA (one family member, one guy from school). One of them is already getting a divorce, but that's an aside. It can work if you're up for it apparently.
I've never escortmaxxed, but it's tempting and I get why people do it. I agree with your strategy that surgery probably is a waste of money unless you're just getting something minor done to reduce your urge to rope when looking in the mirror. Unless you can fix your flaws by 15 or 16, one has already missed out on so much, they're basically beyond salvation.
