Congrats Cil! What I'm most proud of is your confidence and lack of anxiety. You are absolutely fabulous!! Your ex's loss is ours and everyone else's gain.
I guess there are a lot of desperate people out there, this guy seems like one. No, I do not agree it was an abrupt departure. Did he think drinks would go on indefinitely or you would be wife #3 by the end of August? Where were the basic manners to walk you to your car? He's 65 for cripes' sake, certainly old enough to know better. And as for you being uncomfortable, he is clearly projecting his BS onto you, on the first date. If you weren't already inclined I'd say run, don't walk, in the other direction.
Be thankful to him for helping you break the ice and move on without a backward glance, as I know you will.
I would also find it borderline creepy that he'd memorized certain statements in your profile. Yuck. I find your plan a good one. I've been advised to do drinks and if it goes well, suggest appetizers, all the while keeping my sneakers handy in case I need to make a quick getaway. I've been briefed, lol, that this is all about quick meets to see if it's a connection worth having dinner with.
So. That's the extent of my knowledge and advice on the subject. None from personal experience of online dating.
