He probably likes you, but he seems like a bit of a pussy. Are you still in high school or something?

Okay, the context is really important here. If you're friends already and you did something nice or funny he might have just said that in a "aw, you're so nice" kind of way. (which is still far fetched for a friend to say, mind you).

If you're flirty with him, dating or have any sort of a romantic background then I'd safely say he means it and just text-blurted it out.
