I feel maybe its because my responses have been so short. maybe I am coming across as not friendly.

I found I had the same problem. Wife commented that my texts sounded snippy at C. I have started putting a Hi at the beginning of my texts. I also read it outl oud and try to see what tone it would come across as. I am very blunt and have to really try to make sure my txts don't seem short, snippy or unfriendly.
