One thing I've learned in life is that people who lash out often have stuff going on with them that we know nothing about. I'm a little concerned about why said poster is so bothered and angry, and why he would take you telling us facts about your life as offensively boastful? He seems to have everything going his way, reuniting with long lost love - so why is he doing this? I can only guess, which of course is inaccurate, but could he be worried about being enough for HQ, or afraid the bubble could burst? ( I think most of us here with post-bomb-drop jitters, feel a persistent sense that even when things are going well, it all could be taken away from us in an instant. The better things are, the scarier they fear is because we have more to lose.) I hope that those who are close to him will keep an eye out for him. We all want nothing but good for those that are in this unfortunate brotherhood of LBSs.
As for WG - I think you're being sensible, dating is about learning if the other person is a match. I don't think it's Avoidant of you to recognize potential red flags. Sounds like you can just give it a little more time?
