I think she means he needs to giver her highest priority

For men with small kids, that is next to impossible unless they don't love their kids. If they don't love their kids we probably do not want to have anything to do with them. So it is catch 22. Can you give higher priority to your boyfriend than your kid? i couldn't answer that because I don't have kids. But I could not put up with a man who puts his kid ahead of me So I can never deal with a man with kid.
