heartbreak

I broke up with my boyfriend on the 18th of March and he moved on the next day,I've been talking to him,even yesterday we talked,the thing is I'm unable to move on from him the same way he did On Sunday we flirted and later that day i told him that I'm keeping my distance because he's in a relationship,honestly it's hard to forget about him

Hey , so I'm new here i kind of need some new friends coz I'm dealing with depression and just got hurt by my best friend because of her bf and it was my biggest heartbreak ngl Idi what im saying this i feel like I'm seeking attention while I'm not anyway if you ever need a new friend , thanks

Why does the friend you love with all your heart, the one you give everything to, thinking he's the friend you'll spend your life with, betray you and forget everything you did for him? whyy
