Ok I got married last November and it didn't work so it was annulled and is over with. Now I am back in the dating game i'm curious how long quick you should tell someone that you were once married but its over.
While you don't necessarily need to introduce yourself with "Hi I'm (insert name here) I was recently married for less than a year but it didn't work and got annulled." it would be good to be honest about it, at least if you date with relationship intentions. I personally don't see a point to dating if you have no intention of building a long term relationship, but ymmv.
if she asks tell her if not shut up for now. though i'm still single so what do i know. i will just be happy being me and i i find someone to share my time with then great otherwise no big deal.
