I felt exactly this way, and then my wife left me in at the start of this year. The apps are now a complete shitshow compared to when I last used them in ~2020, and I'm not in any kind of scene adjacent to dating. This isn't directed at you (good luck in your marriage), but to anyone else reading this there is hope. I randomly bumped into a girl six weeks ago, plucked up the courage to ask for her number (I've literally only done this once in my life) and we've been going steady since. I now believe in karma and am happier than I've ever been.
