Good evening and thank you for the opportunity to help in answering your question. Based on the information you've provided it really doesn't sound as though you were over-bearing in the least. Having said that, people often perceive things differently than the way it actually is.
As you mentioned one way to approach this is to just backing off and waiting for him to reply. Though another option could be that you could e-mail him and perhaps explain that you may have been over zealous in your approach and that you engaged in this manner due to enjoying his company and wanting to get to know him better. You can also state in the e-mail that you will await his response when he is ready to reply.
I realize that this sounds rather simplistic but the impact can have significant results given the level of honesty and genuineness in your approach. It shows that you respect both him and yourself with this approach. I truly hope that I have been helpful in answering your question and that you found my suggestions to be of benefit.
