Yes, children can be hyper excited, bad mannered and just plain rude but they are children. Learning that standards of behaviour vary depending on who you are with or where you are is a life long process. Plenty reach adulthood without learning. Yes, there are basic manners that should apply at all times but some re slow to learn this, how many rude adults do you know? At seven children still have much to learn. Your partner sounds awful, fancy sulking and being so unforgiving of a child. He could have tried a simple shush or indicted a finger over his lips just something to demonstrate it was a time to be quiet, he could have made it fun. Instead he chose to disengage on a long term basis and to brand the child as bad mannered and rude. He sounds extremely unpleasant, compounded by the fact that he doesn't see his own daughters. That is a clear sign he's not much good at family relationships. Please think hard about your future, being on your own can be a blessing compared to living with a miserable, controlling partner.
