Thanks for all the recommendations, I went with Disney with the kids again and we had a good time!
My W of course, as I expected, got home at 1:30am right after we got back from Disney, from yet another birthday dinner. Oh well.

Anyways, lots going on, main thing is she feels the kids are giving her the "cold shoulder", mainly 3 out of the 4, and she blames me for it. More concerning (and I have to post something more about her later) is D5. Lately we've been spending a lot more time, and I finally took her to play soccer like she had asked me several times, and is growing closer and closer to me.

At the same time, she has been rejecting her mom, which I don't approve of. The other day her mom was going to take her to school, and she refused saying she wanted me to take her. I told her several times to go with mom, but she was having none of it. My W was obviously very hurt. The other day I was on a business trip and came back at night, D5 slept late and didn't wake up on time for school the next day. My W said that the night before she told her she wanted me to pick her up, and that she didn't want to sleep with her.

So the last 2 days I've let my W alone with her to make sure she spends quality time with mom. I think part of the way D5 is reacting is that her mom hasn't been spending a lot of fun time with her ... like "her weekend" she asked me to take her to Disney, thanksgiving, the week of thanksgiving, etc.

This morning my W started yelling at me again, and saying that I'm the cause for her behavior. I asked her to please let me know what I'm doing to make D5 reject her, she couldn't name a thing. She told me I'm rejoicing in it, and that I'm not doing anything to discourage her from behaving this way. I told her to please stop having these arguments in front of the kids, she said "They know everything", excusing talking about these things in front of them. I repeated the same, I don't want this to happen anymore.

So I had to tell her "Look, I didn't want to tell you to hurt your feelings but D5 told me this morning you are mean to her. I told her that's not true and that if mom asks you to do things its because you have to do them, and you have to listen to her".

Anyways, she kind of said at the end "Well, I'm sorry then", but her apology didn't sound sincere to me.

So just now she called me out of the blue, very short call, just to tell me she wanted to apologize for he behaviour this morning and that's not the type of communication she wants to have with me. So I guess that's positive, I think it's the first time since BD that's shes really apologized for anything.
