Last time I saw her, I expressed that I was concerned that he didn't want to spend time with me. He cries when I take him away from his mother, he cries for her when he's "in trouble", and he doesn't even run to me when I pick him up from daycare anymore. She says its just normal behavior, and for the most part I think she's right, but I'm sure she would be singing a different tune if he was pulling away from her.
Keep your chin up. It could be the age. But remember you are an enabler for all relationships you have. Mothers have an advantage their DNA is preloaded with nurturing characteristics. Try to be more nurturing, especially in times where he is upset. Hold him longer, rock him, tell him it is okay. DOn't try to change the situation through his response. Start looking at other ways to be more nurturing and it can happen. A few months ago, my S fell and started crying and he ran to me and not her. It can happen. Bring yourself to their level.
