DH went out for drinks with some colleagues he hasn't seen since Christmas. I asked him if he could leave by 9 (they have been out since 5) so he would be home around 10.
DS has an important hospital appt first thing in the morning and I wanted to go over what questions we need to ask the consultant.
It's also been a very long day with a teething baby who does not sleep well at the best of times, so have been up and downstairs all eve.
He phoned at 9.25 to say he was leaving, he got distracted chatting and was very apologetic. I accept his apology, but just feel like what I ask isn't that important to him.
If it was reversed I would be keeping an eye on the time and say my goodbyes in preparation to leave at the right time.
But then I HATE being late for anything and 'letting people down' (people pleaser) 
Am I being unreasonable to expect him to leave when he says he will?
