One of the hardest parts of breaking up is having to deal with all the feelings that you still have for that person, maybe that is why you feel the need to still have him around you & maintain contact. You're clinging on through habit. I would advice a no contact rule. Cut him out of your life completely, it's the only way to get over him & move on.
His behaviour is alarming & as another person has said, he didn't get carried away in the heat of the moment he actually planned it by booking a room & to add insult to injury he used your money. Then if that wasn't bad enough he used your behaviour as a means of justifying his own unreasonable behaviour.
My ex did the same with me took every fault I had & used it as a means of justifying why he didn't get around to doing things or spending time with me. It's destructive behaviour & the sad thing is you can't reason with them, believe me I tried.
Sadly men like that will never change, they do what they want & when confronted with the consequences they blame anyone but themselves.
He'll never change, he needs to see the error of his ways before he's able to & as you've said yourself he's still encouraging female attention, so he's not learned anything. As for the little bits of hope, he's dangling the bait & when you bite it's all about feeding his ego.
