My DH and I are married. He has 2 sons (8 & 4). We plan to have a child together in a few yrs. And we've discussed in great detail that we want the boys to look at our child as their sibling, not a half sibling. Here's the latest problem...

BM and b/f are on again off again. B/F has two kids of his own (Boy 9 & Girl 6) He doesnt have custody b/c he's a felon and straight up loser. Anyway, SS's were at our house this wkd and SS4 told us the B/F's kid were their brother and sister and SS8 corrected him and said step-siblings. My DH was alone with them when it happened and didnt know how to react. If BM and B/f were engaged and they were explaining, we wouldnt have an issue with this b/c that's techinically what they would be. But considering they break up and get back together, I dont think they should be telling the kids they are step-siblings!! BM and B/f did recently move in together into a 2 bedroom apt with 4 kids!! (It makes me sick thinking about it!) But even still, they are not engaged (that we know of and I'm sure we'd hear it!) and I think its misinforming all 4 of the kids!!

DH & I didnt want to say no they are not and the SS's go back to BM adn say Daddy & _____ said they arent are step-siblings and start some stupid fight, but we also dont want them to be misinformed.

I seriously hate BM, she's a terrible mother and her boys suffer and are acting out b/c of it. They get on my nerves b/c of how bad they can be at times. But I love them more than anything and want the best for them and try and give them the best enviroment possible. I swear they need a manual for being a step-parent!
