He does sound useless @namechangingforthis100 and you are worth better. I feel sorry for any woman who is having to use online dating to try and meet a man, because the online dating pool (of men,) is full of shit. Most men are only out for a shag, and even the very few who aren't, are looking for a woman 15+ years younger. And as a pp said, a nurse with a purse, a woman who will be his domestic servant, and have a shag when he wants it. They don't want to give much back though.
I know a woman right now (age 48,) who has been on 3 dates with men she met on online dating - in the past 2 months. And 2 of them asked her if she can cook, as that's a dealbreaker. The third one asked her if she wants to go to the Premier Inn next door (she met him at a service station,) as he had booked a room, to see if they were 'compatible.'
As I said, the men in the online dating pool are mostly shit. I've been with my DH around 30 years, but if he left me or died, I would never bother with another man again. (I'm early 50s now.) I know a number of women who are 55+ who were widowed after 30-45 years with their DH, and they have tootled along fine since he died, and are quite happy alone. They enjoyed their 30, 35, 40, or 45 years with their DH, but wouldn't have another man in their life if someone paid them.
Having said all this, you do sound a bit intense @namechangingforthis100 . And yes, the behaviour (trying to find out where he really was,) WAS a little bit stalkerish. Clearly you've been burned quite a bit, and this behaviour illustrates that, but most men are not going to want to be with a woman who tracks their whereabouts. It is a bit odd.
