He cancelled plans last minute and didn't reach out to me all through Christmas

I've been dating this guy for two months. He celebrates Yule but was okay with doing a Yule/Christmas mix holiday with me. He said he would after he dropped his son off with his mom for Christmas. He was gonna have his son until 4pm and then he was gonna go with his mom. He messaged me at 9am and said his son broke his leg and they are going to the hospital. His son has a motorcycle and a car hit him when he was making a turn. He said he was probably going to have to cancel plans. This was at 9am and he didn't message me anymore after that. I never got a merry Christmas or Happy Yule or anything. His mom was supposed to take over at 4 anyway so couldn't she have just stayed at the hospital once it was her turn. I did reach out this morning and asked how he was and he said they are doing surgery on his leg at noon. I completely understand he's a dad. I have a kid myself but she lives with her dad in England and I'll see my daughter during the summer. I have always made time to talk to people I'm interested in. I think we still could have kept our plans if mom was taking over but even if he wanted to stay with his son he couldn't call me or anything?

Edit: I don't think it's fair that anyone judge what kind of mother I am. My daughter lives with her dad because she likes the schools in the UK better than the ones down here. Plus she's 17! Nobody would bat an eye if my daughter was 17 and living with me and calling her father a bad father. It's very misogynistic to assume a women is a bad mom just because her kids live with their dad even if they are still in contact with their kids which me and my daughter talk daily.
