specifically mentally ill people who don’t work on improving enough to not harm their partner. i’m mentally ill but im trying to work on myself enough to make sure i know how to deal w my issues as they come up so they don’t hurt my partner. my ex was mentally ill and would not work on it, she had bipolar meds and never took them and made every problem my problem, especially when i had something really important coming up that i had to prepare for (that meant less attention for her so)
