So I was texting with my crush & below is part of our conversation. (By the way we both like each other) And then he said that I was acting weird and it's actually the second time that he says that. But I just don't understand how I'm acting weird?? Is it the way I'm texting is he just reading my text wrong or what?

This is our conversation:

Him:Ikr & do u think u r a qud sis?

Me:With my sister iam but with my bro' oh gosh -.-
