I'm not far out and it was hell but I'm slowly getting there. Mine I've come to learn was abusive and it's still going on now in other ways and I'm having to defend myself and fight to see my children.
I've gone from being fixated on the past and what has happened, what if did this could it have been different, torturing myself over things until one day I forgot to think about it and that I believe was a turning point. Now I'm looking towards the future, the only thing that matters right now is the children but this is a moment in time it will get better.
One thing that was suggested to me was to write down a list from the very beginning, good and bad. I found that my memory of the relationship was skewed and in fact it had always been abusive I just didn't see it at the time. That wasn't love, nobody would treat someone they love that way.
I'm getting used to being on my own and to be okay with that. I don't have friends they were driven away so I'm going out on my own, even just driving to get out.
Now this has made me stronger in a way, a life lesson, albeit horrible and I'll use that going forward so I don't end up in the same situation again.
Things will get better as much as it doesn't seem like it. You're healing, it takes time. Roll with the emotions they are a normal process to relieve stress and heal. The day will come where you are stronger.
