Thanks folks, I've already sorted this problem out today after much consideration.
But I would like to add that I would NEVER consider any inappropriate action with my nurse or any other married man, and the mere suggestion that I was considering it offends me. I never said I was considering it, so I do not need telling it is wrong. Feeling something and acting upon it are two very different things entirely. The point I was trying to make was.....maybe I am just attracted to him as human beings are to each other and not just a mentally ill person having a fixation on my caregiver.
