I also know that I just cannot agree with her each and every time. As selfish as it sounds I also need to consider me here. I cannot be a good father if I am not healthy and if all I do is "give" and neglect me, I cannot be healthy.
Am I wrong? Was this setting a healthy boundary or did I just react to Ex pressing my buttons and hurt my kids in the process?
What does your logical mind say? You took time to think about it and came up with a response that fit the REALITY you are living in.
It seems to me that you made a decision based on good facts. Your kids are not 'into it'. It's likely their MOM is 'into it' and coaxed them into doing it. I think SHE needs these events to feel like she is being a good mom.
If they were TRULY into it, and hurt, they would be begging you to change your mind now don't you think?
I know my kids do not take 'no' for an answer without a fight if they really want something.
QUALITY TIME with DAD outweighs all other things. For BOTH dad and the kids.
I'm only seeing love here. Not 'little boy' spitefulness or anger.
