Can I really do this #2

[Dtrmned]

REALLY need feedback and help today.

Again, the best laid plans blew up.

Decent weekend and even asked W is she still wanted to do Mother's day brunch with all of us. Also said if she would rather just do it with the kids, I was ok with that as well.

She opted for the entire family.

So we did our traditional family morning. Mom in bed, gets her coffee early, enjoys her time alone followed by breakfast in bed with her cards. Overall a great time (I got my run in while she was eating so that was good!).

We all got ready and headed to an amazing brunch. 2 1/2 hours in, W starts making remarks to daughter about looking to date college men. She was jovial, but serious and right in front of me, my daughter and son. She saw it affected me greatly. We briefly discussed as our kids went to the restroom. She said, it's no big deal. I countered I thought it was. Ended the brunch, headed home, quiet and somber. At home, got into it a bit and she just reiterated that she is done and moving forward. Then said, do you want to watch a show? I said no, headed up to our room for the evening. A bunch more to this but mostly just argumentative stuff between us that goes on and on and on.

I don't know, other than detaching more and going more dark how to protect myself from this.

PLEASE help with feedback. I tried to make it a good day, and again, took the bait and it ended poorly.

Is there any hope???
