Welcome. It sounds like your ex-wife is putting you through the wringer. I think it's fairly typical of the ex-spouse to vilify the LBS. I'm sorry you're going through that stuff right now, but it'll eventually get better.
Regarding dating, after my divorce I was gung-ho to get out and date. I quickly found out that dating wasn't all that I'd hoped it would be. After that initial period of dating, I started focusing my sons and doing things that I like to do, and I have to say, I've been happier taking that approach.
