Why didnt my ex gf reply to my text message??????????1?

sponded..? So I was wasted and texed my ex gf, saying I missed her and a crap load of other things. She then texed back asking if it was me that texed her I didn't re3spond, few minutes later she texed me saying she got my text and she put a smiley face on it. I was so drunk I didn't realized its her that texed me back, so I wrote back saying ok and asked who it was. She hasn't responded . Lol what do you think she hasn't replied?
