^ Right. Even if I could get past the sketchiness of the acts and knowingly be a side chick, the insecurity of indefinite other woman status would just eat away at me. Like, I would constantly question and second guess myself and whether or not I was good enough to be a proper part of his life. Waiting for the scraps of his free time, spending holidays alone while he is with his wife/gf...just, no. And for what? It could never never go anywhere -- even if he did end the relationship, I would still remain an insecure mess because I could never trust him not to repeat the same patterns. It's just a futureless dead end. No good sex and/or financial benefit is worth my emotional well-being and self respect.
Nah, not for me. I could barely date someone who was in the closet just because I felt like they weren't able to acknowledge my existence in an actual relationship. And with being a "side piece" it'd just not feel right for me. I'd always question whether they actually feel anything genuine for me, and the idea of being out in public with them is just a no go.
