You’ve waited a good long time since the last fiasco to start dating again. I think you’re ready BUT before your brain gets all fogged up with oxytocin, how about setting a few ground tiles for yourself?

No living together for AT LEAST the first year.

No proposing for at least one year.

Be very wary of damsels in distress.

And given your history, best make sure they are legally divorced and unentangled.
