SO said "most of what comes out of your mouth I can't believe, just like I can't believe most of what your mother says" I've cheated on him emotionally about 18 months into the relationship, and tried to keep it from him. Since then, I've done nothing (that I know of) but told the truth...about every thing. Yet he still brings this up every time he can.

My mother has proven she is a compulsive lier. And just recently served her husband with divorce papers, that she's been working on for the past 6 months.

Is it time to cut strings and leave?
