I have to admit, I am feeling much, much better about my decision to not make a decision regarding whether or not to continue watching Monkey at night after he is returned to his father. Thank you, everyone, for your advice, input, and support! It definitely helps to know that my initial instincts are the same as everyone else's, and my love for Monkey isn't clouding my judgement when it comes to this situation.
I am going to start transporting Monkey to his weekly visits and just get a better feel for what is actually going on here. I'm going to tell The Invisible One that she and dad need to move forward as though I am not going to do this (because chances are, I won't). Right now, I am wearing my "Seriously Questioning Their Motives" face.
I love my little Monkey like crazy. I'm his Mama. He's my baby boy... My little Chunky Monkey... My Patty Cake... But I'm not going to allow my love for that baby to be used to wrap up his case with a nice, pretty bow. Dad needs to prove that he can do this without me. Because if he can't, then he shouldn't regain custody (not that my opinion matters one bit).
