DP and I have a 5MO DD. When I was about 2 months pregnant DP's DF passed away very suddenly an unexpectedly. It was a massive shock to everyone and understandably everyone was very upset. DP did not have a great relationship with his DF, his parents seperated when he was young and his DF was pretty absent and unreliable. DP was the executor of his DF's will and is still wrangling with bits of his estate as he lived overseas when he passed away. DP's DSis was hit particularly hard by it all.
Today DP announces his DSis is upset as she wants the family to be together for the anniversary of thier DP's passing. This is on the same day as my DM's 60th birthday party. I offer to take DD and go to my family party so DP can be with his DSis. He says he doesn't want to. All is well and I respect his decision.
Fast forward to tonight, I have my fourth night out without DD since she was born (home by 9.30 and no booze as I am BF/expressing!! ), and I get home and she is still up clearly tired and fractious and overstimulated (her bedtime is 6.30-7pm). So I have a cup of tea, go upstairs and go to bed to settle her, leaving DP downstairs with a beer.
I wake up at 1am to a crying upset DD with a cold, and discover that DP has literally upped and walked out if the house with no note or message and gone into town for an impromptu drinking session while me and DD are asleep upstairs.
I sent him a (strongly worded) message saying I was really dissapointed in him doing that, as I felt it was selfish, irresponsible and unfair if him, especially when tonight was meant to be my night out, thus ensues a conversation where he says that I am living in a bubble, that it's not a big issue and I'm blowing it out of proportion being ridiculous, and that I am the selfish one because 'don't I realise his DF passed away a year ago this weekend'.
AIBU for being annoyed at him? 12 hours ago he said he didn't want to go to his DSis's to 'remember his Dad', as he can remember him anywhere, and suddenly (after some beers at home) he is so struck by the anniversary of his father's passing that he has to leave the house and go drinking at 11pm at night with no thought about his DP or DD.
