Oh Boooooyhoo I've so been there. I never understand why people do this, but they do. The weirdest one I had, the guy chased me for weeks, really full on and so we had a few dates. He seemed really nice, although had not long separated 
Anyway, three weeks in, he told me to make sure my passpost was up to date, he was taking me somewhere fab for the weekend. Great, got a bag all packed and told the girls so we were trying to figure out what clothes I'd need for all eventuallities.
He arrives to collect me a Saturday lunch time, carrying a huge bouquet of flowers 
Seemed odd, we were going away. Then he asked if there was anything to eat, so I made some pasta. Then .... asked me if I fancied seeing a movie!
What the actual? And here is where it gets weirder. I walked into my bedroom and hid the overnight bag in the wardrobe as I was embarrassed in case he saw it! As if I'd imagined the whole thing! And I went to the fucking cinema! On route,, my pal rings to see if I'm going to Paris or Rome, I'm too mortified to tell her in front of him what's going on, just talked in code.
I dumped him a week later, why on earth I didn't tell him there and then I'll never know. I think I was scared of seeming too interested in a weekend in Paris, when the real issue was his total lack of explanation.
I still look back of that and laugh. The flags were all there of course. But why couldn't he just text/call and tell me plans were changed? Madness.
You will pick yourself up in no time, the guys who can't be honest about what they want are really not worth anymore introspection. This just frees you up for the nice ones who are still out there, and there are loads of them. xx
