Okay so recently I've been like texting my ex because we have a mutual friendship, but the thing I'm worried about is that he always finds me at school and stares, looks at my social media accounts and copies stuff just to talk to me, and he STILL talks to my friends and his friends about me. We broke up in August due to complications, but I feel a little weary and uncomfortable? Is that justifiable? Or am I just overreacting? Any advice could help!
