Divorce and custody are always treated separately regardless the cause of the divorce, regardless who was "at fault".
Custody is usually given to the mothers unless they don't want it or it can be proven they are unfit to be the primary caregivers.
Custody is usually given to the mother when the chilren are young, moreso if the children are girls.
Considering the routine of daily life, your access rights are rather liberal. Do you think it is practical for your daughter to live with you 3 days and your wife another 3 days?
Whatever your ex wife demanded, the judge only ordered you to pay $350/mth for your daughter. Which is, in all honesty, rather fair, supposing she is under 12.
Clearly, again supposing what you post is the truth, the judge and we can agree that she was beyond ridiculous in her maintenance claims.
Us? Funny? We are all victims here! Go pick a fight somewhere else.
