Is he stringing me along?

So I've been dating this guy for over two months now and the other day I decided to ask what he thought about us and if he wanted to be in a relationship. He hesitated then said "suuure" so I took the hint.

I thought everything was going so well. We get along like a house on fire. Laugh at each other's stupid jokes and seem to genuinely have an interest in one another.

He claims he doesn't know if he's ready for a relationship but has been thinking about it and "leaning towards yes"

I've met most of his family already and have spent a pretty good chunk of time with a few of them with him.

Am I crazy to be thinking this might be going nowhere and he's just stringing me along?
