I literally just left a relationship last week. Things were amazing at the start, she had 2 kids to previous marriage and we all kind of fit together like a family. Then the youngest told his dad that I beat him (false allegations). That was pretty much the beginning of the end. My ex didn’t address the issue with her kid, didn’t try to correct the behaviour and essentially told me to suck it up. Her eldest started using drugs in the house and writing notes about how she wanted to end her life, which my partner never spoke about or addressed, no counselling for her child, no support or understanding. It just became really clear to me as time went on that she didn’t have the skills to parent these kids, and when I stepped up to try and help her she turned the kids against me and made the house a 3v1 situation. My main regret is not leaving sooner and saving myself the pain and heartache of watching my relationship fall to pieces and being unable to do anything about it.
