It takes time but eventually you may feel differently. I believe in these situations we can only take so much. Eventually most people have enough of being treated badly… it can take a long time though to get to that point.
There are aspects to the addiction and any abuse sustained by partners that I think may be relevant also such as co-dependency, trauma bonding, enabling etc. I know I have suffered and suffer from these… I’m working on myself. The way I’m being treated is not love and I deserve better.
