Annoyed with husband mother

My husband called his mother to let her k ow we will not be going over for new year's. He told her the reason for not going but she didn't believe him, she said "I knew you weren't coming anyways so it doesn't matter " my husband got upset because she said it with an attitude. My husband told his mother in a calm nice way and she talked to him with anger. I know she's mad at me because her daughter and I have little problems but why take it out on my husband?? He literally just got back from overseas, he's only seen his parents twice. Why are you being such a fucking bitch?????!!!!!

Just a little update and I feel bad. Nobody was going to come and that's why she got an attitude. We're going because we feel guilty.
