Hey. So I've posted a couple of times lately. Got a girls number at the gym, went on a date.. went really well and made out a couple of times. Towards the end I suggested we go out again next Sunday and she agreed. She text immediately after the date saying thanks and that she had a great time.

Since then she seems to have gone quite cold over text. She text me first the next day and I replied. After that I went to call her and she said 'sorry im in a lecutre.' I said something tongue in cheek like 'I told you I'm going to be a distraction' and her reply was very blunt like - 'well clearly not cause I didnt asnwer' I put 'enjoy your lecture' with a winky emoji and she replied two thumbs up.

Later on that day I text her to ask how the rest of her day was, she read and didnt reply. I was going to be and (i know I shouldnt of) but I text again and she replied saying 'hey sorry, had a busy evening bla bla bla'.

This morning I messaged an inside joke to which she just replied with laughing emoji and now I have messaged her this afternoon and she hasnt opened it but has been online.

Have I done something wrong here? What should be my next step?
