Am I wrong?

Tonight I went with one of my good friends not talking down on her or anything but she does mess around with a lot of guys. By good friends I mean my bestfriend of 9 year's. My boyfriend DOES NOT LIKE THE PEOPLE SHE HANGS OUT WITH. She hangs out with older men and we're only 17. Anyways i hadnt been out in a while mainly because I'm always with my boyfriend. me and my friend went to this thing called the cruise where cars just drive on one street. A lot of guys go.. as well as girls. I always tell him where I'm going and tonight I didn't mainly because I knew he wouldn't want me there so I know he's feel a type of way. So I told him I was there and he said you went? And he got mad and started being so mean. I'm still young I wanna have fun you know? I'm not being a hoe. I'm just in a car cruising down the street with my friend while there's guys and stuff. Idk, he was like you get mad at me when I go to ******* house and don't tell you and look at you, well yeah so hes upset
