DP's sister is 8 months pregnant and had her baby shower today. Quite honestly I don't understand them and didn't want to attend. It was a 4 hour train journey each way due to the sides of London we are in and my side had rail replacement.
I said to SIL a while ago that I may not be able to attend and I don't have a car as I work in central London (thus commute). She basically insisted DP drove me and came to which he accepted.
Now the shower has occurred and DP is angry at me and not talking to me because of it. I had said I was happy not to to, he chose to drive me (2 hours and accommodation paid for by MIL) so we could go. We never see SIL so this was the first time we saw her pregnant. He thinks I should have figured out the driving thing myself (haven't driven in 7 years) and he said he will let me know of the next weekend he ever wants to spend with me.
I find it all unnecessarily mean. AIBU?
