being me implies that I play the guitar for a living... Much more, I play it also for fun, for my kids, to say I love you, to pray God, to relieve my hearthaches...
I'd say that in a relationship, you have to take your loved one as a whole, and you have to know if what annoys you is a part of him or just a temporary thing.
My wife knows that I would be as sad if I lost her or if I lost my ability to play the guitar, she accets me, and in return, I write her love songs once in a while....
Be strong, your guitar will help you through this
