I agree with other posters. I think you jumped the gun and tried to get into a relationship way too fast. Some of us need to take it slowly.

If I were that guy I would have likely done the same thing. Some of us need time to earn people's trust before we get too close to somebody.

Some people are naturally more cautious and less trusting of people and others have been hurt by other people and as a result, need a chance to build trust. Forcing somebody like that into a commitment so soon is a huge red flag.

I would suggest getting to know him better first.
