* I am committed to taking care of myself so that I can be the best partner I can be.
I learned this one through "osmosis". I've always been a fan of letting other people learn my lessons for me. I don't need to burn my own hand just to learn that fire is hot. I became a fan of the Anita Blake series because I felt like Blake was all of my bad traits exaggerated and none of my good traits. So when I saw her get herself into blindingly obviously stupid situations that she could have easily avoided, I used her stupidity as a guide for What Not To Do. Similarly, when I saw my metamours bend so far over backwards to accommodate and enable their partners' dysfunctions, I saw that their lack of self-care directly led to the relationship's toxicity. When my metamours didn't take care of themselves, they were unable to provide the best source of support for their partners in need. When they didn't take care of themselves, they lost the ability to recognize unhealthy relationship patterns. When they didn't take care of themselves, they had no defenses for preventing others from harming them. It turns out that being a good partner, someone who has the emotional resources to care for and support their partners and who has the internal strength and fortitude to maintain good boundaries, requires being in a physically and emotionally healthy state - or as healthy a state as possible given any individual circumstances.
Taking care of myself should be a goal all on its own. But sometimes taking care of myself is a means to an end. Sometimes, some of us need to be in a good state for someone else's sake. My sister was on a downward trajectory involving drugs, alcohol, sex-too-young, and lack of education. But then she got pregnant. Suddenly, her own health became of paramount importance because she had someone else to care for. I'm not saying that my own health takes a backseat to how well I can serve someone else, but I am saying that my ability to be a good partner is related to how well I take care of myself, and these are a list of commitments intended to remind myself of how to be a good partner, so it's included because it's an integral part of being a good partner.
