Let's be honest here, given that we have a partial, biased peek into anon's life, there could be a myriad of reasons that make that apparently small gap a far more serious problem. He may have a notoriously ugly face or body, he may suffer from heavy anxiety at the tought is becoming intimate with another person as a result of trauma, he may have atypical nonverbal communication, he may not want to form a connection with someone he doesn't really have much in common with, he might be a mysoginist. These possibilities would limit his options a lot, and looking for someone when you're supposedly doing everything right but still having so much trouble is painful.

If not saying Anon shouldn't look for tools to actually find a partner if he wants to put in that effort, but that we shouldn't underestimate his difficulties.
