There are several posts where we have talked about this and other issues relating to kids. have you done a search and had a look around? I think that they might be helpful to you...
My story with Mono is an example. My boy is 7 and Mono came into our lives when he was 5. We have developed into a family of three adults and one child and my husband nerdist and I have other loves as well that have come and gone over that time. None of them have been seen by my boy as pivotal as Mono. They have been seen as family friends and that is worked out fine... mind you we are sure to not show affection around him in order to be respectful of that image in his mind.
