Broken

I am broken. i may be toxic. in my life i have never found someone that loved me back and i think it's because i'm too clingy...clingy like someone that's drowning. my relationships start out great but something always happens...i find it hard to trust the opposite s** because of my past failed relationships...and everytime the same thing happens: i try to trust them but they always betray my trust. i try so hard to be the best partner/lover i know how to be and i just want that in return.

why do i always fall for people that only want to hurt me?
