sole custody with reasonable and generous access
i'm ok with reasonable, but generous considering the other parent involved here sounds way to easy peasy, way too lenient. it says your boundaries and schedules are fluid and he has access on demand. as he does NOW with afternoon calls about seeing the kid tonite.
considering how this person has been acting lately, i think 2 hours every other thursday and some weekend time is much more appropriate!? remember the kids have to endure that time with an active alcoholic demonstrating signs of mental health issues.
IMO, i don't believe for one minute he is driven by wanting to see the child as much as he is driven by wanting to continually invade and to a degree control your space, your actions, your time. the child is a means to an end. he isn't bucking for Father of the Year.
