25wks pregnant fighting on Xmas

On the 22nd of this month I lost s close family member. He was the head of the family and the one that made Christmas christmas. Because this was my first Christmas without him, and having only lost him 3 days prior I told my partner that I’d like to spend the whole Christmas Day with my family. He then guilted me, saying that his family has given me gifts and what not so I went to there family Christmas for the morning. I was meant to pick him at 1 to bring him to my families Christmas but instead at 12:30 I got a message asking for me to pick him up at 5 instead. I was annoyed purely for the fact that my family had organised the day where we do our usual games on Christmas from 4 o’clock so I’d be missing out as it’s a 25 minute drive to where he is. Anyways I sucked it up after telling him we can spend tomorrow together instead and went and got him when I asked as he made me feel guilty yet again because he had gotten me an expensive gift. I pick him up and I’m waiting in the car for 15 minutes before he even comes out.

He comes out and he’s as drunk as anything which okay cool, but we went back to my families house where he lasted not even an hour before He wanted to go home because he was too drunk. I drive him home and I have my little brother in the car, the whole way home he kept opening his door at every red light and taking off his seatbelt telling me to fuck off. We get to his and his anger gets worse he starts punching walls throwing things, falling into me yelling at me to fucking leave. He snatched his phone and keys out of my hand nearly fell down the stairs because he was so drunk and aggressive. He was so angry mind you I’m 25 weeks pregnant, I tell him I’m leaving as my little brothers in the car and I’ve already missed my families Christmas & then he starts sobbing saying that I don’t love him? This Christmas was already hard for me and he’s made it harder. I don’t know what to do. I’m at my wits end he’s always having emotional outbursts and I have no idea how to help it or how to leave. It’s not healthy help
