This sounds like a strange situation. Why did he feel he needs to make you dislike him? Anyway the real question here is do you want to give him a chance. Perhaps he was afraid of a relationship with you and was looking for a way to push you away but all that doesn't matter if you feel you like him enough to try and make this work.
I say follow your instinct. If you feel good about this relationship go for it and see where it leads.
