To make some things clear to you,
1) I am here everyday. I have just finished the process of moving in with my boyfriend into the house. YES, it happens EVERY DAY.
2) I have talked to the child. When I ask him what he does, likes to do, or does with his dad, he has nothing to say, even when I prompt him (do you play video games? Do you like baseball? Where do you want to go for summer vacation?) The only thing he talks about constantly is his pretend phone. When I ask him what he does with his dad, it's "nothing" (because that's the truth). When I ask him what he likes to eat, it's the same ("nothing" or "iceys"). I haven't asked him about getting hit or anything, since there aren't signs of that, but let me tell you - that kid ISN'T doing ANYTHING.
3) I have never seen the father make a meal for him. Even in the evening, just before he goes home to his mother, where he has dinner. At around 6, the father will eat a burrito while his son sits and watches. If he asks for food, the father says "go get a pudding pack" or "go make some cheesy bites" (they're this microwavable pizza thing). I will say that, every now and then he brings the kid a plate.
Please, if you have any questions about the 'situation' let me know. I thought I had given a pretty clear picture of what was happening, but if you'd like an hour-by-hour summary, I can provide that too.
Just for reference, so you know: about twenty minutes ago, the father got up. The son has been coloring a picture of a truck we drew together while I was writing this. The dad looked in and said nothing. I think he went to the kitchen, but I'm not sure where he is now. Once again. If I was the kid's mother, it'd be one thing - but I'm not. I'm not even a babysitter. It's ridiculous.
