It's good you are so self aware and can accept your situation to find a level of contentment.

No partner is perfect so being in a relationship requires evaluating tradeoffs and deciding where you can compromise compared to your ideal. To do otherwise or expect someone (or yourself) to change is unfair to them. Unfortunately sometimes we think we can deal with something but ultimately can't - that's part of the self discovery and vulnerability/heartbreak of relationships (because we can of course be on the receiving end too). Really you have to be willing to embrace a person's flaws and take long term joy in doing so, and also have gratitude for them doing the same.

So if you know all that's not really for you, then good move on your part.
