Help i met this girl today i think she likes me but how do i know for sure?

I met this girl today and all she did was smile I gave her my number and she texted me like 15 mins later n tellin me how cute I was and thanking me for making her morning by putting a smile on her face. She also said that she loves my name but the bad is she said she's in a relationship and that her man was crazy. I told her that I'm not tryna wreck a happy home cuz I believe n everyone having an equal chance n I'm happy to make her smile and hopefully theres many more to come n I asked doesn't she think every relationship deserves enough trust for the partner to have friends of the opposite sex as long as its casual convo but she hasn't text back in like 3 hours now:c I hope I didn't screw up my chances. What do you guys/girls think did I blow it? Does she seem to like me but is just committed right now.? Should I not be so aggressive? should Ijust drop her a text every now and then to keep me on her mind or say nothing until if she texts back? I think she does like me but she's just trying to do the right thing which I admire and understand. If she didn't like me or want me to contact her she wouldn't have texted me right? All help is greatly appreciated thanks in advance!!!!! Btw my names not Michael king lol its just something I posted to ask this question
