I wonder if you're agreeing to go along with the relationship vibe too soon without doing your own groundwork? You should be evaluating the men as much as they are choosing you.
If the pattern is really that bad maybe your picker is wrong.
Obviously there are future fakers out there, but if its happened 5-10 times rather than 1-2 times I'd think you were getting caught up in emotions and overriding early warning signals.
After the first physical meet, I'd manage the pace of the dates...don't do big dates or message all the time, treat him like a new friend you don't actually fancy and don't have to "win over". Continue to meet others.
If you're meeting, give him a day and time that suits you and an activity that suits you.
Either something YOU want to do. Or something simple like a walk or a coffee. Or let him know if you've got a random small practical task like moving furniture...if he's into you he should be keen on helping. Seeing you should be enough.
Don't be rude, be nice and polite but just show up and be present.
(I don't use expensive dates out as a sign of interest, its too easy to stick a card down on a night out!).
If he refuses to meet unless he's doing X on his terms on his timeline, he probably just wants an activity buddy or dining companion or "fun".
This will eliminate a lot of men and early dates who see you as a convenience option..Let them go! The filter has worked.
The ones who stick around after 3 months would actually be into you.
