You seem to think he's up to some cunning plan. I hate to break it to you, but while 10 yos can be manipulative in certain situations, I think they are more reactive and perhaps a bit impulsive.
I think he feels empty--he's trying to "fill" himself figuratively with praise and respect from his father and I view the overeating as a way to physically try to fill an emotional void.
I'm sure that going back and forth is hard for him. And of course he's going to miss his father--what an awful situation for him.
But the adults created this mess for him, so it's up to them to help him. Does his father spend one-on-one quality time with him? And I'm not talking about you all together--trying to make him be part of your family--and I'm not talking about watching tv together. I'm talking about just the two of them going out to dinner, going to a park, playing a game, etc.
I think parents in a divorce/remarry situation are often too focused on themselves and how the kid needs to fit into the life they are trying to create with other adults when they should be focusing on the most important person in this huge mess--the child.
Thank you... I didn't think of that.... Its weird though because he "cries" he misses his daddy... he never said he does not want to be over.. but I will discuss that with my husband and see what he thinks. Maybe your right.. Maybe that was the enitre plan. I know he has been trying to break us up because he sort of wants his mom and dad together but he "likes" the man his mother remarried? I guess time will tell. Thanks again.
Maybe he got what he wanted in the end? To "not be picked up"? Maybe he wants to live with his stepdad and his mom and was trying to devise ever and ever more unpleasant ways to get what he wants - one home where he lives all the time instead of going back and forth and back and forth?
