Talk to him. If he's interested in you and you are in him.. why bother counting a few days? What's the point?
Seeing that you talked and joked about the whole calling who thing. I do not see any harm in a text mentioning that you had a great time and thanking him again. Sounds like you both hit it off well. I wish you a lot of luck.
:) Awesome. I hope you said you'd like to go.
Just text him as I believe u wouldn't want that u could miss a great guy plus he mention is 21st century so just go for it . I would for sure!
ya go and text him, there is nothing like that boys should move first
