Here's my experience. Whenever I came out of a relationship, I was confronted by how much I'd forgotten about single life.
You've got to kiss a lot of frogs. That takes energy and open-ness. Especially if you're an introvert; I don't wish to jump to any conclusions about you,
@hnla394, but an introverted nature can be common among us couch-and-cuddle types. It tends to take a while for introverts to heal from a relationship, too—and to put ourselves back into good working order, emotionally.
You'll need that emotional resilience as you re-emerge into single life. It takes thick skin to weather the rejections, and thick skin to dish out a rejection, too. But that's part of life. In a relationship, I'd fallen out of practice doing both of those.
Coming out of a relationship, your emotional energy probably feels low. Find ways to top up your emotional gas tank as a single man, and you'll be in better shape to venture out into the dating world.
Did your date turn out to be a dickhead? A dickhead date isn't a failure; it's one step closer to finding your prince. More frogs = greater chance of success. It takes energy, but you can find your frogs in lots of places.
@Ninjato and others have suggested gay sports teams, volunteering, social groups, meetups, and a broad circle of friends. Even if you don't find Mr Right in those places, the rewards are immense.
But I wouldn't stay away from the apps entirely. If I went in with realistic expectations (and my boundaries healthy) even a fast fuck put a little bit of energy in the emotional battery. A lot of those fast fucks were fine men; I admired many of them, and the memories of our encounters still puts me in a positive frame of mind. I'm glad I kissed the frogs first, and sized up their prince qualifications later. Sex ain't everything, but it's almost never a waste of time. Picking out curtain material isn't a first-date activity.
Sometimes, dating feels like work. Not always easy work, but it's rewarding work. It takes emotional energy, but it doesn't need to be an emotional drain.
My warmest best wishes to you.
