I've done everything for Christmas, literally every single thing. DP hasn't bought a single present or contributed ANYTHING. Hasn't even asked what I've bought the kids or showed the slightest bit of interest. He went to bed last night, I stayed up finishing sorting everything. He has a lie in, I was up at 5.30 with eldest DS (SEN) trying to calm him and stop him waking everyone up. Youngest DS wakes up so I said we can go downstairs now but need to wait for daddy to open presents. After some persuading DP comes downstairs. He's already grumpy and snappy with me and the kids (eldest is hyper). I ask to borrow his phone to take some photos as mine is broken. He's being rude and I'm getting upset as kids are starting to open presents. He starts filming on his phone and I tell him to stop but he won't. I tried to get his phone and he yelled at me and wouldn't give it to me. Carried on filming. I missed the kids opening their presents because I was so upset and he just sat and filmed the whole thing. He didn't even deserve to be there the selfish fuck. I'm LTB I hope you all agree IANBU
