Gave my crush my number the day he got over a girl? Remotely interested?

I almost NEVER talk to him except for this one good convo a few months ago... but went up to him yesterday 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 out.

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....His friend told me after that this one girl- who my crush called a "b****"- actively led my crush on then once he started liking her back, she stopped talking to him. But his friend said he got over her the day I gave him my #? I don't think they're connected.. but what if they are?

Do you think he might be remotely interested? How do you think his situation with this girl might influence his situation with me? Do you think the two events could be connected?
