Randomly gave a guy my number in his class?
Besides one really good conversation with my crush a few months ago, I don't talk to him much besides saying hi sometimes or if I need something. I went up to him before his class started and said "Hey... want my number?" and he was like "Sure, yeah". He actually texted me after school! & we talked about like.. everything and he seemed pretty engaged in the convo but then his answers got a little shorter and a little more spaced apart.
In the end I said "I gotta go start on my homework, but you should talk to me more in person. You seem nice & really interesting :)" and he was like "Thanks, you too :)"
But- maybe I'm over-thinking?- He didn't seem really excited when I gave him my # yesterday or when I said hi to him today. What do you think will happen? How often should I text him? What usually happens in this kinda situation? How interested does he seem to you?
