I think a lot of guys (including myself) bail out of a potential friend/partner because we don't know the expectation on the receiving side.

Usually when I give someone my number, they text me an hour after they left :') haha
I expect a text the day after actually. He doesn't need to wait a week to ask me out, a couple of days later or even a day after it is fine.
No need to bail if you don't know what girls expect, that's like saying: I don't wanna start a relationship because I might do something wrong. That's just BS. If I wanna text a guy, I text him. If he doesn't appreciate it, tough luck, I won't do that anymore with that guy.
