I think as long as you have filed something legally that dating is fine. Jeeze my STBX had his AP live with him for a few months after we S. Now he's onto GF number 2!
I've just started dipping my toe in the dating pool. I think it's healthy to give yourself 6 months to a year after a S. To at least get yourself healthier before dating. Otherwise it can often just be a rebound relationship

Accept what is...let go of what was and have faith in what will be.
