My story, what to do next.

couple of thoughts on today.
Brother has a birthday party today. (side of my fam. that wife doesn't get along too well with). Yesterday, I call and ask if I would be able to pick up the kids and take them to the party for a couple of hours (it is her day). Here is the convo. W "they never get together for his birthday why are they doing it now?" M IDK W "well sure, are you going to sign the card from all of us?" M sure W "o.k just text me before you are coming to get them and I will have them ready". She also tells me to let my mom know that she will drop the kids off at 8:00 am tomorrow.

My question is that W and my mom definitely have tension over the whole sitch. along with past problems. My w has made it clear that she doesn't appreciate my Mom's coldness towards her and that I never stood up for her (in the way she wanted) in the past. IDK if I should remind my mom that she needs to respect W's feelings and treat her fairly, or if it is better to just let them handle it themselves. That way their is tension, some chaos. ect... Remember W said last week that when she has thought of reconciling with me, she keeps being reminded of how bad my family treats her and just knows it could never work.

Opportunity for me to step in and make it right? any thoughts would be great.
