I'm not sure if this is the right place, but couldn't think quite where else to post. I am new to MN posting (and have just dipped a toe in a couple of discussions that looked safe up until now ...) but have been lurking for a long time. I would like some advice, especially from those of you who are either mums with XDHs/XPs and DCs or stepmums who may have faced this.
Sadly (and not for want of trying in my younger years) I have no children. I do have 2 lovely and quite grown-up stepchildren (DSD 24, DSS 17). I have been married to my DH for ten years, have known him for 11, and was not the OW. I have a good relationship with the DSDs and DH is very close to them. They live with their DM quite some distance away, but we see them regularly - rarely together these days as for the past few years they have visited separately either alone or with friends, as they are different in age and interests.
My DH has been diagnosed with cancer - of a kind that is life limiting and incurable but which will follow a pattern of remission and relapse over several years - the number of which depends on treatment response.
The time has come now to tell the DSDs. Should I/we tell their DM first or should we treat them as adults and talk to them that way? DH's relationship with his ExW is not good at all and they rarely communicate. My relationship with her is distant, but she has always been nice when we have met in the past. I am happy to talk to her if that is the right thing to do, either before or after we tell the DSDs.
Does anyone have advice?
