Detachment to me was the realization that whatever XH felt or did had no bearing on how I needed to live my life. He was a bug in a terrarium. Mind you, I actually had a bug in a terrarium (4th grade project for my son that was supposed to last 2 months) that lived 2 years because even though I was not emotionally attached to it, nothing in my care or my kids care will be neglected.
How did i achieve a measure of it? A little at a time, as i observed his behavior and modified my own. I set boundaries that if he crossed, he got the consequences. He only tried crossing a few times. He knew i meant what i said. Really, what did i have to lose by taking care of me? And while I filled my life with distractions until I could separate my outcome from XHs outcome, I still did laundry and made meals and was couteous and kind and asked about his day. My detachment came when I decided to be in charge of me. It started a few months after BD, but I wasn't fully detached until nearly 2 years in. So it was a decision and a process and time for me.
How did I gain a measure of it? It started with finding distractions from the hurt. Driving off road with people who actually cared if I lived or died, unlike XH seemed to be. Coloring. Hiking. Anything I enjoyed that gave me true pleasure, if only for a short time. There was no fake it till you make it for me. There was find what I like and do that for me to get to my destination. But I know that about me. I'm not good at pretending, but I am good at finding something real I like. It's amazing what driving through dangerous terrain with complete strangers who treat you better than your own husband does will do for your mental state. As I found my personal center, I could step back and look at my XH as an interesting thing to observe, because that guy was not my husband. So I could still care about this new guy in my husbands shell, but my love was not for him. I would never have given this guy a second glance.
And here I am today. I stood until. My until was the divorce. As far as I'm concerned, I did everything I could think of to save my martiage since he was home for 18 months, but he had his own plan in place to file for divorce as soon as S turned 18 so he wouldn't have to pay child support. So I'm good with how it played out, but I was a lucky one. I could support myself and the kids, I had enough time to completely detach before divorce.
The guy XH is now is no one I want in my life. Might he become someone I would? Maybe. And that's how I know I'm detached. I don't want to talk to him just like I don't want to talk to other people who disrepect me. But I don't rule anything out if he should ever approach me with any intent of getting back together and if I were still attached, I don't think I could get past his prior actions. I would like to believe there will be consequences for his actions, but if there aren't any, meh! I have too much gong on in my own life to care about that. Should he call and ask for help, I will still give it expecting nothing in return. He's still a bug in a terrarium right now. Interesting if I see him do something, no matter to me if I don't.
