about three yrs on and off. the last straw for me was trust. i felt myself becoming someone i wasnt. i questioned everything. felt like i had to check up on him, and search for the truth in everything he said and did. and id have to prove to him i knew the truth because i think most the time he convinced himself of his lies. letting go is hard, but it only gets worse. it starts with the lies, but can lead to verbal abuse, physical abuse, suicide threats, etc. its hard to leave but harder to stay.
