I like him.. but I’m so aggravated.

I went on this date with this guy a few days ago, he was really shocking, really nice, open my door for me, brought me flowers, went out to eat, and I’m not use to that I’m just use to guys who want to chill or don’t do any of that! So two days ago he said he wanted to come see me, I said ok. His cousin(a guy) was in the car and I had to sit in the back. And idek if it’s me or if guys act more cocky In front of their friends, but I was trying not to be rude because it was pissing me off. I want to see him, because he’s leaving and going back to school but I’m also still aggravated and over him already and I dont why I’m so easily aggravated by this.
