Am I not a priority?

How come my boyfriend sticks to his plans on going out with his friends but never sticks to plans with me? He told me he was gonna take me out on a date today, never even mentioned it AGAIN but he goes and calls his friends to make plans for the week. The last time he promised me a date, the day of he didn’t mention it and left me at home to go play basketball. I don’t have any friends, I stay home with our daughter so it makes me feel really bad.
