Lost and confused

Amber • 17 years old. I've been with my fiancé for 2 years and 7 months😊

My fiancé always says that he's "going to bed" pretty much in the middle of an argument at night and then when he wakes up, he pretty much acts like nothing happened, or he won't bring it up at all but he will still sort of have an attitude. But today, he is acting like nothing really happened. And I don't know how to respond because, I don't know, I'm just clueless. I don't know how he feel. Like, I don't know if he is still pissed off at me or if he came to his senses, or just let it go. I mean, I guess he let it go, right? 😫I don't know
