I Loved Someone That Didn't Love Me

For me it's not about being friendzoned... or being in love with someone who didn't know I exist... he knew me very well and was no friend, he was my boyfriend who was a sociopath...
He pretended to be in love with me and pretended to do everything for me and everything was so believable that I fell in love deep with him but I realized his feelings were all a lie and they were only "word-deep" it didn't extend beyond his empty words...
