Today you decided to talk to him about it. "Uhg, let's see if I understand. Do you think I'm stopping being attentive? It's absurd, I just have too much work, better go think about your things somewhere else." he said and then rolled his eyes at you and went back to his phone, it was always on it, is he cheating on you?
