I fell down an incel-adjacent rabbithole when I was a teenager and young adult and while I was physically isolated (lived with my parents in the suburbs but my parents hadn't bothered to teach me to drive, so getting around was a royal pain in the butt. Realistically I could've done more but youth truly is wasted on the young) I then for "reasons" socially isolated myself by avoiding online communities where i could have met people. I had really bad acne that brought my self-esteem to zero (in hindsight the acne was about the 5th least attractive thing about me at that time) and was struggling to complete a college degree in the wrong field while also failing to work enough to be able to afford to move out (again, hindsight 20/20 I had things I could have done but didn't)

Because I didn't interact with anyone outside of my household, my social skills never grew and probably deteriorated. I was depressed and felt trapped, I believed myself to be "too autistic" to do things that could help, and it was all around a pretty unhappy time in my life.

I happened to meet my now-wife on an online dating site, and we've both reflected and determined we were both in similarly bad but different places at that time. She had gained a bunch of weight (I seem to have a wider attractive range for weight than most people so this wasn't a problem for me) and was moving on from her nth abusive boyfriend. Honestly my lack of social skills at the time made it so there were times where I flat out said something incredibly hurtful without realizing it. She's since told me that she put up with that because "at least I wasn't physically abusive" (single dudes, the bar you need to meet is so, so low)

Anyways we both have since grown a lot as people and have both grown into fairly functioning adults. We both have more to grow (we both really need to get our respective executive dysfunctions under control), and sometimes we've grown apart, but we've kept growing back together.
