DD1 is in her early 20s and just finished uni and lives in a flat-type place, but she comes home when she has time off work. She currently has 2 weeks off, so has come home.
DD2 is going into her 2nd year of uni and lives at home (commutes).
DD1 has known her boyfriend for a few months and he lives closer to our house than her flat-type place, so they have spent a lot of time together. One day they are getting up early and going on a day out, so she asked if he could stay here and I said yes (I have met him and he's lovely).
DD2 hasn't met him yet and doesn't really want to, there isn't a particular reason (doesn't really give one) and has said she won't feel comfortable with him here, she doesn't know him and if she needs to walk to the bathroom, go downstairs, has asked if he'll be around and we said well yes, maybe. She has decided she isn't comfy with that and will be booking to stay in a hotel but likes to add "it should really be them booking into a hotel".
I'm undecided really. I still think if she has a problem and I and her dad do not, she should be the one to sort herself out.
She has social anxiety so that's why she's a bit iffy about meeting him, there's no untoward reason.
Thanks.
