I know, NoDirection, and the R between you and your son will strengthen, even more, It amazes me, how some people believe that kids, can't see the truth, or they will be just fine with everything. Ha, that is the biggest crock, I've ever heard.
Kids can sense when they are loved, and being treated right. On that note, they also know when they are being used as pawns just to inflict pain on one parent. I know your son is young, but even at such a young age, to hold so much aggression toward your STBX, should really be a wake up call to her, but as we both know, they (the STBX's) live in their own twisted world. I say let them. But don't take our kids down with them. I will not, and I know you will not either. Take care
