Bit of relevant background- I drive, dp doesn't - that's not a situation we can change unfortunately. The impact is that transport arrangements are entirely covered by me. I regularly drop him and dcs off and pick them up at convenient spots for them then go off to park the car. I cover all long distance family visits, airport runs, school runs and clubs etc.
Anyway, Dp has membership to an event which happens most weekends. He usually goes alone as it's in a city about an hour away but it's good fun to watch so occasionally I go along with the dcs.
Today I'd booked event and train tickets not realising the trains weren't running so it was a replacement bus service. It took no longer but was cramped and uncomfortable- none of us got to sit together.
Anyway at the event while dp was off somewhere we bumped into friends who offered me and dcs a lift home - but they only had 3 spare seats. We could either go straight with them or wait 1hr 30 for the bus home and then walk 25 mins back from the station. It was freezing so we accepted. I didn't think dp would mind too much as I would then meet him at the station. He did mind. It turned into an awkward and horrible situation in front of other people.
I know in isolation I sound selfish and perhaps should have said no but then we'd all still be walking home in the rain now rather than the dcs being fed and in bed. Honestly, this is an utter one off, I can count the number of times I've had a lift with anyone else in the past year on my fingers. I'm a bit disappointed dp couldn't see this and just go with it for once to make my life easier.
Sorry this has got long - Aibu??
