Hi NicG,
I wish I had some helpful advice. I am in a similar position and have really struggled with supporting my partner through recovery while maintaining a “normal” family life for my children.
I’ve found that coming on here helps, knowing that I’m not alone. I’ve also taken steps to prepare for what I have to do if their sobriety doesn’t work, which I take comfort in.
It really isn’t an easy position to be in but I try hard to keep calm and let the resentment pass as it’s not good for me to hold on to my anger about the situation we’re in.
I would just say, that it’s been vital for me not to suffer through this on my own. Tell people you trust and ask for help.
