This sad determinism is bullshit. While it is unlikely that i will find a partner, for reasons i would rather not talk about, it may happen very fast ‘out of the blue’. Nearly happened to me, but it did not work out in the end. Which was again pretty random and surprising. What i am trying to say is, do not beat yourself up about a future that is literally unpredictable and try to enjoy life as much as possible with what you have got.
