You know, I bet that over time he may just turn around. I know it's hard now. I bet because you lived together for a long time that right now he's just testing out how he does without you. It might take some time, but I bet he will turn around.

Now, my husband and his mom, when she doesn't live with us he talks to her al the time. When she lives with us, he doesn't talk or spend any time with her! I know it drives her crazy. But, I know that he wants to be "king of the castle" and his mom wants to be mom, but he's grown now so he just hides from her as a resolution. For some reason they get along better when not living in the same house. Not sure why.
