okay so my boyfriend and i broke up about a month ago and i keep telling myself that i'm over him and i have literally moved on but when he posts pics of him and his now girlfriend and they look all cute with their matching outfits and perfect matching skin tones i feel like i break a little inside. like my heart literally hurts when i see it. i'm completely over him until i see them together again. what is this feeling?? how do i get rid of it and over it?
