He is a lovely boyfriend from what I can tell and tries really hard not to provide fuel for her jealousy...but we have family friends with daughters and when they visit she can't cope with it and gives DS a really hard time. I have said to him that jealousy is irrational and that there's not a lot he can do - it's good that he is reassuring but I really don't want him feeling guilty etc. He is already avoiding female friends to avoid upsetting her
What do I say to him? She has her reasons for feeling insecure (unsettled homelife) but I so want to protect DS from the fallout of her insecurity.
