For me it was also the API issues. I hated the normal client and only used sync. When they shut down the API I left. Unfortunately I feel like my /all is mostly political and the niche communities I follow don’t have enough content. I’ll always be a lurker.
I agree with the others but here is some advice when you are happy being alone.
Don’t let the search for a gf become a large part of your life again. I was on all the dating apps and whatnot thinking I was ready to have a gf and I still think I was. But the search started consuming me i spent an hour or two a day reading profiles and going through pictures to try to find the right one. i would read the bios of girls and think about how perfect we would be together and swipe on them. If a girl swipped on me even if she wasn’t up to my standards I would swipe just because… maybe if I give her a chance… it would work.
After maybe a year of that, numerous dates and spiraling depression I realized what it was doing to me. I found a half way decent dating app and canceled all the other subscriptions. Then I just started trading it as a game, 5/10 minutes here or there throughout the week and that was it. I was in a much better place. Fast forward 3 months and my gf actually swiped on me, fast forward a year and we are expecting our first kid.
