She gets it: sexual compatibility matters! If you're not keeping up with their needs, LET. THEM. GO.

Just because a partner isn't sexually compatible doesn't mean they're selfish, just means they have different needs

Absolutely agree, and my issue is simply quantity. I'm coming from a place of severe deprivation right now so my view is extremely biased, but my feeling is that it's selfish for a person to expect their partner to both remain committed to them AND continue to rely exclusively on them for their sexual needs, when those needs are nowhere close to being met. If a person really cared for someone, they would want them to be happy. They certainly wouldn't expect them to remain in a situation that was causing them misery. To my thinking if the dial can't be turned up any higher and no other accomodations are made, the situation is broken. If the other partner doesn't see a problem there, they aren't worthy of commitment in the first place.

You keep saying how your partner is selfish for "not wanting you to be happy" but you're being more selfish by expecting them to sacrifice their happiness for yours.

If you aren't happy in a relationship then it's your responsibility to get out of it, not to try and force a person to change who they are and what they want so you can get your dick adequately wet.

I don't expect them to change, nor would I presume to force them to. Intimacy under duress is even more of a lie than honest neglect.

My sin, if anything, is being too timid, too passive, too complacent. Everyone is entitled to want what they want and be who they want. What I want is reciprocated physical and emotional intimacy. I won't die without it, but I won't be whole without it either. If my other half doesn't make me whole, that's the definition of a bad fit. May or may not be completely my fault for ending up here, but it's 100% my responsibility for being here now.

I admit it is wrong of me to put the onus of ending things on the other person. You're absolutely right that as the aggreived party, that responsibility is wholly mine. I can curse her blind spots but it's irrelevant. The core issue isn't why or how this is broken, it's how and when I GTFO, sate myself with a string of flings and then move on towards something tennable. In the mean time, I'm afraid imgflip users will have to suffer my whiny, single-minded memes for a while. 😐
