How do I prove to myself that I can do it again?

So I have been single for most of my life up until 29 I then met and dated a girl and that relationship ended last year. I’m on the autism spectrum and I’m now 33 so first I didn’t think that relationship would happen I feel in ways I stumbled into that but how do I really convince myself that lightening can strike twice and I know that’s a really sad analogy but when you have very poor social skills you can go many years with friends or a romantic partner.

How do I prove to myself that I can do it again?
