W took D13 to get glasses this afternoon. When she came back she thanked me for paying for them. I said "It's no problem, I need to take care of my girls, I'm their dad".
She got angry and said "I don't say things like that to you when I do things for them".
I realized that she took as me putting her down in some way. I wasn't, I just wanted to say that I take responsibility for the girls well being.
So, I told her that I didn't mean to make it sound like we're competing, and I also said that sometimes she does say defensive things.
