It's definitely an issue and the only thing she ever brings up. I have offered to work on it with her, Given her options and asked for her input. The problem is I feel like i am dealing with two children which is pretty much the feedback she is getting from everyone on both her side and mine on the issue. She has similar issues with her own S but then the maternal instinct comes in and they make up but the problem is when it is my S she harbors the resentment. Obviously she knows there is no option of choosing her over my S ( she too is a parent ).
One thing i cant understand is if it is all the child then why is she so cold to me. i find it hard to believe that is the only issue but is all I have. She has brought up some stuff regarding me but nothing major and it always comes back to my S.
It's difficult to know if the issue with Son is a primary problem or a symptom of another problem, but if I were you I would read some books on THAT particular dynamic to see if you can get some insight. There may be issues that occur in blended family situations that tie in with the issues of respect, validation, etc. If you do some reading about the subject you may note some correlations. She may feel that you undermine her in front of him, don't let her have input in parenting him, etc. I wish I could be more helpful, but I have no experience in that area.
