Opinion

So my ex husband and I have a daughter together. Wednesday he did a no call no show on getting her for his overnight visit. No call the next day saying something came up, couldnt do it, nothing. But today, i get a text from him asking when my son gets out of school. Its my sons birthday, not his son, im guessing he wants to tell him happy birthday. He left when my son was 6, hes 10 now. They barely see each other ever so they dont have a relationship. In my mind im like how dare you text me without acknowledging the fact you really just skipped your day, knowing it was your day cuz i text to confirm you were getting her, and ask about my son. I would like to ignore his text. Opinion.
