I got out of a three year relationship in July-August. The guy I used to date is now telling me he has lost feelings for me and I’ve noticed on social media he is just following and comment on girls things again. I feel so horrible and worthless. I don’t understand how someone can move on from a long relationship that quickly. People say that it gets better with time but it just gets worse with time for me. 
I feel so horrible and stuck. I’m extremely depressed
