Suggestion needed about future

In relationship with her for almost 4 years. Although relationship is kind of toxic but there're lot of emotional memories. She's bit of abusive when in anger and on the other hand I also made lot of mistake by giving hope & all. It becomes kind of hard for me to handle her anger. Now I trying to fix things up for our future. I tried connecting with lot of my friends & psychologist, but didn't get balanced solution. By balanced solution, I mean both of us should not suffer unfairly and live life peacefully. Both of us come from lower middle class family and both approaching 30. she's not working.

1. I have few responsibility for my family as well. So, one of my friend suggested "to do breakup and not continue because of these family responsibility. If I go with her, then in the end I have to sacrifice one thing in my life (sacrifice means not good future), either my family, her or my career. and not being true to my family responsibilities in future will give me more guilt than breaking up with her. and they told It'll become hard for me with family guilt. In chess, sometime you have to sacrifice queen to win. Also, they asked me to read geeta that duty comes first than anything else. and family didn't make any wrong and deserve the best in future."

2. My judgement around this is kind of messedup right now. Although i understand the logic part of it and completely agree with this. but Emotional part of this is kind of making me feel guilt. that i did very wrong to someone. and Even i understand that it'll be hard/impossible for me carry all these burden in future, still I think lets go with her just that I dont want her to suffer things.

3. Above 2 solution feels very biased to me. In both solution, one of us have to suffer badly. Posting here to get your solution. I know both type of people exist here. Someone will feel more for her and other will prefer family.
