Relationship

How to get over someone you care so much about ? But he doesn't care & it's just hurting me i got no close friends and no one i can talk to. All my life was focused on him but i see now i was wasting my time because he doesn't give a damn about me & im so sad & keep getting my feelings hurts 😞 I can't stop crying. I feel so disappointed & stupid he never cared as much as i did
