I'm pissed and not talking to my bf because he didn't cook dinner
Why did you think he was going to cook?
Because last night we agreed for him to cook.
It is understandable why you would be upset, you both agreed on something and then he didn't do it. Partners should keep their word and do the things one's partner ask for otherwise the relationship is in trouble.
I am still really upset about this.
What he did is wrong, maybe something came up and he was late or extra tired. Do you think you could ask him to order take out for dinner? I am sorry this has happened to you.
