I posted a few weeks ago about an issue with my ex's gf texting dd about her relationship problems and making comments about my ex's and mine decisions to DD. Well, I thought we had it figured out after we spoke, but I couldn't have been more wrong. Yesterday, at DD's birthday party at the pool she got in the water, took DD from her friends, went over to where I was sitting supervising the kids and started hugging and kissing DD like there is no tomorrow all the while glaring at me like "look at what I can do". I had 3 other kids to look after (their parents were not in attendance), so I couldn't do anything but sit and watch the show that she put up. My ex was totally disengaged, sitting in the hot tub, so he didn't even see what transpired. I talked to him later and I told him I feel hurt, helpless and saddened by this situation. I am at a loss as to what to do. I'm pretty sure this woman is trying to get my ex and I to fight as well as trying to turn my own kid against me. What do I do?
