Think I came on too strong, what next?

[TwisttheLeaf]

In your shoes, I would text him with a note asking him how he's doing, and that "you're sorry if he felt you were coming on too strong", ending with an "I hope to hear from you soon" (or something of the sort) to close it out.

Then? Wait and see if he replies over the course of the week. If he doesn't? It's time to move on.
