Sometimes when we text we can have random conversations about nothing that last hours or all day, she will even keep the convo going. Other times no matter what I try the best I get is a lol or an ok. Same as in person she will tickle me and start play fighting. Sometimes she will do it in response to what i say or do or by herself and the next time nothing. She will also make inside jokes that have sexual conatation or do sexual things so I don't think she is just a flirt.
Our random conversations have even lasted days where she has fallen asleep and continued it in the morning
