I dated a girl for five years that I truly believed I loved, and maybe I did, but she convinced me she loved me. Turns out she had lied to me about everything about her and she had been cheating on me since the start. When I found out she had been cheating I didn't even break it off I tried to fix it then she dumped me. I used to be confident, but she made me realize I'm not attractive, not funny, not smart, not interesting, and am weird (something I used to think was good). It's been over a year and have not been able to get anyone to talk to me, or even return a smile. beginning to wonder if I even actually exist.
