HELP ME!?!?

Ok so I've been Rping with this one guy since 2012 the same guy the entire time. And since we started he has always been slightly rude and overbearing but that could be baca use I'm really really shy. Anyway with in the last 6 months I have noticed that he has been a lot nicer and sweeter  to me and started call me babe and baby and stuff. Tonight before I started to crash from my sugar high(long story) I spammed him with a whole bunch of emoticons. After I apologized he started to say that I was really cute an he wouldn't stop. I felt like turning into a tomato from how bad I was blushing. I think I have a crush on him now what should I do :(((

Btw he is biual just to clear that up right away...
