My ex husband

When we were married he cheated on me, now he is with that girl. We have to talk about our child together and he told me the other day that their iclouds are synced together so she can see everything I write. What the heck?? Why would she want to see what I write my ex husband about??

Now knowing this I use it to my advantage. I can tel when he takes her off the iCloud sync because he tries to flirt towards me, which I decline, but when she’s back on he’s rude as crap. So I text him about things he talked about when he didn’t have her on the iCloud sync and I know it’s just eating her inside. Karma bitch.
