matters of the heart 7/7/22

yk, sometimes i wonder why i'm so attached to this two faced liar who was someone completely different when we were together. 7 months passing by and i'm still just as in love with him, or maybe i just think i'm in love with him. i believe i committed to someone that he's not anymore. i loved that version of him, but now he's not that person. and i can't keep doing it to myself. he says he still thinks about me but he lies to everyone else saying he doesn't care, that he just feels bad for me, and i can't tell what to believe anymore. he says he lies so everyone will leave him alone about it and he's apologized, but i really can't tell. someone help. i'm so happy when i'm spending time alone and i truly love myself but i can't figure out if maybe i'm the problem.
