How the fuck do you people date? What the hell am I doing wrong?

I’m 26, I have 2 degrees, a job I love, I’m moderate, an adult, I’m happy with my appearance and myself (for once, after a lot!), I have a house I rent and impending (for sure, fingers crossed) moderate financial stability for the rest of my life. I have no kids, no debt, and am (for once, after a lot of work) physically and emotionally healthy and healthy (for once). I’m not, nor have I ever been, a “fuckboy” or a “pussy” or an asshole. I’m a genuinely nice person with good intentions and a huge (for once) social circle! My parents are even happy for me! (for once). I’m not, nor have I ever been, a loser (for once)!!! Godammit, I’m an adult, how do I not have a partner before I’m 30? How do I not have a kid of my own?! What the hell am I doing wrong?! Why do I date (for once) for, then get dumped (for once, again, after a lot of work being good and a genuinely good person) after 6 months?! Why do I get rejected (for once, again) when I ask a date (for once) to go out, then she ends up on Bumble again? What the hell am I doing so wrong? Even what the hell am I doing wrong with my appearance? I’m not disgusting! Godammit what the hell am I doing wrong?! Why does nobody want me?! I’m not too fat, too skinny (for once, after a lot of work with my health), too small, too big, too anything! I’m not too nice (for once, after a lot of work) or too much of a dick! (for once, after a lot of work). What the hell am I doing wrong?! Why does nobody want to date me?!
