How did you tell your spouse?

I found out my ex filed after he called the police when I showed up with the kids for a regular visit. I thought we were still trying to reconcile and I had been bringing the kids over every day to the condo that we had lived in (owned by me and my parents). My garage remote didn't work. I was able to open it manually and found my key didn't work in the door. I called the phone and he didn't answer, but his truck was in the garage.

By this time I was getting a little angry. I tried the front door and knocked repeatedly. A police officer showed up and he showed me the paperwork that my ex handed him. What a nice way to find out, with my kids in the car. What a wimp he was. What I thought was strange was that he had already filed the paperwork before we spent the day together with the kids at Legoland.
