HOW AM I UNGRATEFUL

I'm as irritated as it gets, I'm literally about to break up with him. He gets these stupid ass petty moods all the time. I'm sick of it. I'm sick of being aggravated, getting upset, all of that.  First of all, I'm 19. My mom is strict as hell, she thinks I be at my friends house and won't let me stay out overnight anymore. My birthday is Wed, and he so-called planned, something. Which he didn't, he always says he will do stuff and never does! So I told him I'm not staying the night, I literally stayed last night and it was a waste. So he just cancel the plans. Like who does that? I'm sick of this petty shit. My brain is exploding. I couldn't even control myself I'm so damn irritated. We use to vibe and click now 4 months in( I don't even remember our exact Dating day ) I'm irritated our my mind
