separated 6 months and want back in... where do single people even start?

so the divorce papers arent quite done yet but were living apart since november and im finally feeling human again... the thing is i actually miss the lifestyle. we did it for 4 years as a couple and i loved it. but i have literally no idea how single ppl do this... do you just show up at a club alone? do single mens nights exist outside of cliche? i'm in manchester btw and the scene here is mostly couples from what i remember. anyone done the solo re-entry thing successfully... feeling lost tbh
