I dated my ex for four years. For the past 2, we lived together... We broke up 2 months ago and he moved out. He still receives mail at my house and has been coming to pick it up. Due to such, he's aware of some symptoms that I was having and keeps asking me if I've found anything out. It turns out that I do in fact have a malignant tumor in my lymph node. We don't talk much, in fact I don't speak with him except for when he swings by once a month (soon to stop as I'm moving next week). The question is- do I mention it? He won't find out from mutual friends, as we really have none. My concern in saying so is that he will try to get back into the relationship. Guys-- would you rather know or not?
