Divorce is final. I kept the marital home after buying out the ex. 50/50 custody and we live close.

She has this new, annoying habit of texting me at times when she knows I am either not home or at a kid activity away from home saying, "oh the other kid forgot (something totally not important and trivial), so I'm popping into the house for a minute".

One day, when I was out of town, it was that she just "needed" at that very moment some car wash spray left in the garage.

I've said that I don't want anyone going into my house when I'm not there, but she completely disrespects this.

How to deal? I really don't want to file a trespassing complaint, because we have a custody arrangement that works and I don't want the kids dragged into taking sides, or having unnecessary drama. Which I think she is trying to provoke here.

But my house (which I had to buy back from her after my income paid it all off initially) is my house, and I don't want anybody just showing themselves inside whenever they feel like it. And using the kids as an excuse is just ridiculous. Go buy car spray or a $2 USB charging cable for your own house instead of showing yourself into mine. I've moved on and don't want her poking around my business ever again.

Advice??
