I was told once that two good people will never hurt each other. Ok actually i was the one scared of a relationship that's when I was told this. Then it happened, I started loving him more and more as time went by and still do.
Integrity is choosing your thoughts and actions based on values rather than personal gain. You need integrity to STAY in God. Because whatever you do for your personal gain will KEEP you in pride not in CHRIST.
Detoxing from an unhealthy relationship is a process and it takes time. There will be good days & bad days. Just remember, it is very difficult to be an emotionally healthy person while closely attached to a toxic person.
