I Wasted My Time On Someone

My ex boyfriend broke up with me last year, a couple of weeks after my great nan died and also several days before my 15th birthday, needless to say I was in a pit of anger and loneliness, its taken me this long that I wasted too much time on a cruel person, he always kept from me hanging with my friends, he would check my phone and at moments if we were out, he would straight up ignore me until either he wanted something or was in a surprisingly good mood. I should've broke it off a long time ago, serves me right for going out with an older boy of 16 I guess.
