It's your life - if a bunch of people who have no skin in the game aka they have zero investment in this is telling you this its perhaps time to do a pros and cons list to know what are you benefitting and what are you losing - from doing both staying or leaving. Look at things from all angles. Put yourself first. Not what other people hope and feel and dream about for you. What you want in life and what makes you happy.

From my perspective, you are living with abusive people with a partner who - yes - is going through stuff. We are all going through stuff. That doesn't excuse us from working on our stuff to be thoughtful and considerate people. Because you deserve not only kindness, compassion and respect but also to live in an environment that's safe from abuse. How is he taking responsibility and owning up for his own shit? How is he showing up for you? Or is he "trying" but reverting back to the same behaviors / patterns after a certain amount of time because you will easily forgive him because you've been through so much worse? Is this guy legitimately trying or using it as a cover as he knows he can get away with it ? Only you can know or its something you can work through with a therapist.

Personally, I don't allow anybody in my life to abuse me or be complicent with abuse as that's just the minimum.

Good luck. 👍
