It's opposite for me. I pretended it was no big deal and had normal few months. My family went out of their way to help me, and they still do. But I didn't need emotional help (so I thought). My dad even commented on how amazingly well I took it.
But as time passes by, I get worse. It's actually less about separation (I went through all stages of grief already, I think

). I actually enjoyed alone time. But my depression now comes from the fact that I feel abandoned by my friends. Noone we know h as really been divorced, so they didn't know how to deal with it. But they've basically just left me, it seems. I go days without any communication with my "friends". Now I am at a point where I barely sleep 2-3 hours a night and therefore, can hardly perform at work.
In a strange way, for me it was less about my wife's repeated cheating and the sense of betrayal and the feeling of being abandoned. I am having a real hard time dealing with the feeling of being abandoned by my friends. I was married for 10 years so their wives are friends with my wives, perhaps that has something to do with it. But I was hoping at least a couple of them (ya know, ones I was friends with for years and years before either of us got in a relationship) would be there for me.
I didn't mean to vent, but just throwing out that ya, I do feel like a fish out of water even though for the first many months I didn't.
