I share joint legal and joint physical custody with my ex. However, due to the baby's young age, my child spends the majority of time with her mother (for now). However, my child's mother (who is single) has numerous children by several men, drinks excessively, and fails to include me in decision making, despite the fact that we share joint legal custody. On top of all of that, the mother bad mouths me to her OTHER children, which will certainly have an impact on my child. I have a much more stable job and can provide far greater attention to my child because I have no other children. Over time, how can I arrange for primary physical custody to be given to me? I am concerned this will be difficult since I am a man.
