My Situation - any thoughts or ideas

[XYZ]

Her actions continue to confuse me. Two things happened today. First, she sends me a text saying "I'm done at 4:00 today, would you like to take the kids to Mexican for dinner". I respond, "sure sounds great". She proceeds to tell me about how traffic should be lite. I just sent a smile back.

And then second, my mother called this weekend to ask about some family event plans for Christmas time. My W questioned the age appropriateness for our kids. (My W questions everything my mother does). I told her over the weekend that I would make a call and check. I did so today and sent the following email to W:

"I called the Cirque people and spoke to them about about age-appropriateness. Seems totally fine. I'm going to tell mom that I'll come with the kids. We'd love to have you come with us, but I'll leave that up to you. Just let me know."

She replies: "I'll attend"; I reply to her reply: "Sounds good. I'll let mom know. Thanks."

Do her actions sound like someone trying to leave? I'm so confounded...
