Is it right my partner put my FB message on read?

We are sort of just friends lately but still consider each other partners. Regardless of that, I told him on FB about my long day out (Replied to his FB message) and it also included my niece's older guy boyfriend having LUPUS now. I got nothing from my man but put on READ. I found it rude and cruel like. We are in the midst of taking a relationship break but still talk and text and see each other sometimes. What do you guys think of this guy?
