Mother and I share joint legal custody. Mother has physical. Mother has child on weekends. Son frequently shares stories of hopping into bed with mother and boyfriend to watch tv, when vacationing everyone shares same room, boyfriend often attends sunday "family dinners", daughter spends weekends babysitting boyfriend's dog, son is now friends with boyfriend's niece and nephew, boyfriend attends family vacations (grandparents, mother, brothers). It is my understanding that the courts frown on young (under 6yrs old) children being brought into "new relationships". The boyfriend has been around for only 9 months and only came into the picture after most recent court appearance. Assume pro se appearance in court.
