5 min,
I allowed her to handle her own problems and to suffer the consequences of her own actions. The truly amazing thing about that was that it made things better between us rather than worse.
When I stopped being her doormat and showed her I was strong, it put us on an even plane. I was able to lead rather than follow when I needed to do so.
In my case, it took me being comfortable allowing H to fail at times, instead of swooping in to rescue him. I still struggle with this, finding things he can be allowed to fail that won't adversely affect me. Paying bills - I can't let that fail. Personal projects that only reflect on him, not both of us, yes, I can let him fail.
I had to let H fail out of school, be ridiculed by friends for not working while I was, and basically realize HE had to make some changes himself. We hit a really rocky period right about 10 years ago where I was contemplating leaving and made steps to allow me to do so. I bought my own car. I tried to make it clear I was doing things with or without him, that I'd enjoy him joining me, but would (try to) not get super hung up on if he was going along or not. When it became clear I could leave anytime, but only had stayed because I still chose to do so, he changed a bit. It was still slow, and even today, I still face rages where his issues are all my fault, but I think it's a little easier to not take as much hurt from the accusations, and for us to move past the rage to actually working on an issue.
