To say no to DS having GF stay over night?

[Danceasifnooneswatching]

That's it really DS 20 GF19. Have said I don't like it, I feel uncomfortable and have younger ds's to think of.

He says I am old fashioned and behind the times! And it'd none of my business as its his room.
Aibu??

oh god i could have written this. Ds is 20 Gf 19 he does not get that I like the house to just be family sometimes Gf is lovely and tbh he stays at hers more than she is here but sometimes when he announces (not asks) that shes coming over, sometimes for tea too with little notice my heart sinks and he can tell I am not happy but can never see that there is an issue.

It's 'your house your rules' for me too. I can never really relax when I have visitors - I feel the need to be 'the host' to them. I would not be happy to be forced to be the host endlessly.

If he wants to move someone in, then he can move them in to HIS place - the one he should be looking for right now. As for his saying you are "old fashioned and behind the times" and that it's none of your business - well, he would say that, wouldn't he? It's the 'best' he can come up with, because he's got no real argument.

Oh, and LolaDontCryOverSpiltEggnog made a VERY good point on how it can affect the younger siblings (Fri 19-Apr-13 09:27:02).

Not a single parent no but he is not my husbands child, It seems that it's a difficult thing to deal with in lots of families, I never thought I would feel like this as we are very close and I thought I would be ok with him having a GF to stay over!!

I think if he was an only child I may feel differently but am not sure, this is a part of having a grown up child that I wasn't prepared for.

Got to go through this another 3 times.
