There is this one plate that I've caught feels for. She's 100% not relationship material though, but I can't help out I feel. I will never take her to anything more than a plate which is what puts me in a delima.

Since she's just a plate i can't expect her to not fuck/date other guys. She just turned 30 so it's unreasonable to expect her to just be my plate and stay single forever.

How do I stop caring that she's fucking other guys and will eventually have a boyfriend? I have other chicks fucking but that's not helping. I don't care about the other girls fucking around AT ALL. It's just this one.

How do I really accept and internalize the "she's not yours it's just your turn" mindset? Any books to help with my issue here or attachment in general?
