I would try to fix the bed situation with sex toys or a new position.

well what I understand from my experience if you are continuously failing to fulfil her needs that will definitely make her sexually frustrated. Sex is the basic human need so it cannot be avoided. No matter how much love she do to you or will do but she will look for sex too. So its her choice what decision she makes but I personally think she will move on one day.
