"My children come first."
For a parent, that sentence can sound responsible.
For their partner, it can eventually sound like:
"You will always come last."
Children do have needs adults are responsible for meeting.
A healthy adult partnership also needs time, voice and protection.
The two should not be turned into permanent competitors.
Needs come before preferences
A sick child may need the parent more than a planned date.
A school crisis may change the weekend.
