My WAW confuses me

[Bunches]

So when W dropped off S again last night she asked about plans for the weekend. I gave her the run down and she seemed disappointed, aparently she was thinking about trying to grab him for tonight to take to a friends but I had already planned to take him to a church event tonight and its my night so I didn't bother offering to change plans. It also bothered her that I was taking him to this kids entertainement place nearby, saying she had wanted to take him there. I let her know we had gone recently and he had a blast. She let me know she was bothered that she didn't get to do it be involved but she would not be 'mad at me for it'. I found that ridiculous but let it slide. Showed her his easter basket I setup yesterday and she made some remark about not leaving her any room to put anything in his basket. Then I mentioned a plan I was thinking of for his upcoming birthday. I wanted to take him to this waterpark nearby and invite family members that were neutral to the situation so there is a comfort level with all of us attending. She seemed okay with the idea but again she was obviously bothered and said it was because she had always made the plans in the past and felt left out.

All in all I felt very accomplished for my planning and taking care of S needs. Too bad it bothers her, I'm not going to let it divert me from making plans.
