I can't answer your last question because the only thing I know about being healed and moved on from the trauma is that I'm not there yet.
I've definitely had those feelings of REALLY wanting a companion. Not a serious relationship, just a man to talk to, date and make me feel like a desirable person. But as the saying goes..."broken attracts broken". I belief that is entirely true. The only guys I attract right now are messed up liars. I met a guy a few months ago (not online) and all that I've learned so far had helped me identify a lot of red flags. I'm pretty sure he was a pathological liar too. The old me would have stuck around until the lies were proven beyond a doubt but the new me cut it off immediately.
Sorry for rambling but what I'm trying to say is that if you jump into the next relationship too soon it's inviting disaster.
Guys who want to date someone still struggling with their last relationship are usually predators.
