I just don't understand it. She sends me funny emoji's with her communications about herself to me.

And she sends me videos of our daughter and her progress updates.... It's hard for me to make this transition into "friend / dad only zone"

I imagine I'm reading all into this that there is the want to connect beyond my daughter......

I've only responded to the texts with short comments about my daughter like "she's really cute" or "go P go!"

I've read that I shouldn't is there harm in replying?
