Am I wrong??

Hey so I’ll start off by saying I love my boyfriend and his family very much, I’m not out trying to cause issues or be frustrating or cause conflict between anyone. So maybe someone can ease my mind or maybe give me some advice cause I feel like I’m losing sleep that I need over this.

So for the last couple weeks my boyfriends mom decided to invite all of us including my three kids to the beach for like a week, we all took that time off and we even planned to take photos I even got outfits for the kids and he got an outfit for himself and his mom bought me and dress and a flower crown. Because as of right now I’m 17 weeks pregnant so we wanted to get some food family photos as well as maternity photos. Now I’ve never seen this before or had to deal with this but it’s really hard as a person to tries to fix problems or resolve small issues have to go through this cause it makes me either cry or have really bad anxiety.

I’m a hairstylist and his mom set up an appointment to get her hair done by me this Sunday, then we were all going to leave Tuesday afternoon. Well last Tuesday I got in a really bad car accident and yes I’m okay now but I don’t have a car cause it was totaled. So I had no way to get to work to do anyone’s hair. My boyfriend asked me if I was going to work Sunday cause his mom was asking and I told him that my boss took me off the schedule for the next week and this week cause of me not having a car, he said okay and that we should probably tell his mom and I said yes we do need to tell her. (Me assuming, one of us is going to tell her) next day rolls on he comes back from being out with his boys and tells me the trip is cancelled.

His mom cancelled the trip for our part of the group because I didn’t call her and tell her that I wasn’t going to be in the salon due to an accident where I would have no car. Then me being a person trying to understand this, I asked him why he didn’t tell her when I told him and he said that he thought I did. So miscommunications okay fine, but seriously his mom said I’m a horrible person basically and that she’s done with me and she doesn’t want to talk to me ever again and she blocked me from her phone. I tried everything I could to talk to her and still she doesn’t even want to try and talk to me or hear what I have to say. All of this because she got a call from the salon saying her hair appointment was cancelled. The grandma of our baby completely shut me out cause of that. I literally cried on the phone talking to my mom and dad trying to wrap my head in understanding what I did wrong. And the worst part of it is that now my bf is upset too cause we’re not going, and his mom won’t talk to me. He didn’t even back me up when he was talking to her instead I feel like he made it worse cause he was like telling her, ( Well I don’t know why she didn’t tell you or call you) I’m sorry but he has a mouth too he could have said something the day I mentioned that I’m off all week. I know he messages her all the time.

Any ways can anyone help me or at least shed some light to all this I’m feeling really emotional and could use some advice or good vibes.
