This probably won't help, and because my situation is very different, it's easier for me to detach. But this is what I say to myself when I start freaking out about what my ex might be doing.. I just say "Whatever" in my head, over and over, and I try to find something to do.
That probably sounds ridiculous, but it's as simple as telling myself I can't change anything that's happening, I can't change what he's doing, I'm not a part of it, he needs to do what he needs to do, etc, etc. And most importantly, I just block it from my head..
Sure, this doesn't work all the time, but for the most part it helps. Even if he IS doing all the things that you imagine, can you change it? No. So why think about it. Why let it change your day and how you feel?
