Weekend Back At Sengkang

Been 2 weeks since I had a tiff with my mum in law and yet, I am still mad at her. Guess this time, she has really gotten on my nerve.
Anyway, went back with my husband to stay on Saturday night at his place as we wanted to watch WWE on his cable TV. However, I did warn him if his mum is hostile or heard complaining about me to anyone, be it on the phone or in person, I won't hesitate to make him and his mum lose face. I also did verbalize that I am still furious about her biasness and prejudice against me. He reassured that his mum wouldn't provoke me if I don't provoke her. Good, let things stay this way.
True enough, I didn't bother to communicate with her neither did I even give her any eye contact. I just treated her as invisible and didn't even greet her as I entered the house. The mere sight of her just pisses me off right now.
My husband challenged me to stay mad at her for 1 yr or more and I told him, we will see how. For now, let things remain this way. I am not sure if this attitude would affect my marriage next year but I am really unhappy about the way she has chosen to handle things to be biased against me. I also did told my husband that even if chose to go back to his mum, I don't blame him but don't expect me to nice to her as long as I am still mad at her.
If he ain't able to understand this fact, then he isn't fit to be my man, right?
