Should I text him this? 10 pts?

I was texting the guy I liked...he asked what I was up to tonight and I told him then said, "what about you?" My text was funny so he just replied "You're awsome". He seems to really like me but he is also flirty and a charmer so I can't always read him. Does that mean he is avoiding responding to "what about you" or no? What do I say back......or just drop it and see if he texts again later? Also, he thinks I have a boyfriend but we just broke up! So I think he is afraid to contact me sometimes. Should I say "I'm a free woman now...nothing to do with you, I promise"? or wait til we can talk? It's a lot to spring on him in a text maybe
