My s/o is... idk

Jasmine
So for a month now me and my s/o have been going back and forth about me having conversations with another guy. I've apologized about it multiple times but it's still bothering him. The last week or so we've been doing good. Trying to put everything behind us and all of a sudden today when I don't text him good morning, he gets super mad. He ask why I did not text him and I said "idk I just didn't do it, I knew I would talk to you later." His reply was "you can pillow talk other guys but not text me good morning." Next thing I know he's going off cursing and stuff. This situation has caused some serious issues. Smh
