Nightmare Rick
I had that situation about 3/4yrs back, I was the only one in a relationship, and then almost exactly when mine finished, ALL my current close mates got into ones, so I was fucked as nobody hardly ever went out.
Luckily my mates at mo are totally 101% irrisponsible, even the ones who are 25/26, so only 1 of em even lives with a bird, everyone too busy shagging sluts to want to be with one bird.
Also a bonus a lot of them are a bit younger than me, so thas gonna help. In the usual group of mates go out with it ranges from 18-26, so its not so bad.
Ill just have to keep on top of the situation, and keep the group of mates big enough that wen the ones get all responsible, I got ones to take their place, I dont wanna get in that situation again, itd ruin me, as im so shallow
