Speaking to you as someone who spent the entirety of his 40s alone, wasting endless hours in pursuit of romance online, bed-hopping like Blanche from "Golden Girls" on ecstasy, I can say the old adage is true, "how you gonna love someone else until you love yourself?" Sounds like you have done the incredibly fucking hard part, learning to love yourself - hurrah! You are in a great spot, even if temporarily isolated. Stay strong and patient and optimistic - good things (and good sex) will happen.
