I was in relationship with this guy, he took me for granted, I knew it but I was so in love that I didn't care, I messed things up b/w us but tried my best to solve it, I fucking tried so hard, I nearly begged him not to leave me, but he did I didn't stop I tried many times but he didn't care. then on instagram I saw there was a girl in his profile pic, most likely his girlfriend, I want him to regret losing me, I know it's childish but that guy ruined me. I want him to miss me and beg me to come back just like I did. Any tips? how do I make this work?
