My DH had a DD when he was very young. She is now 32 and we have 2 little ones (6 months and 2). Everyone gets on well.
She lives in a city about 1 hour away and has a great job there. She is quite negative though and does a lot of moaning about her life although she has lots of good stuff! She has just bought a place in said city. But says she really wants to live in London which is unrealistic due to her job (not really many in London!) And cost of property.
This is going to sound v horrible but she comes stay with us every single weekend and I feel like I don't have any space or privacy. The house isn't that big and I'm at work so weekdays are frantic. If she were a child I would feel completely differently.
The thing is it's not to see us, it's to go to parties and come back at 5am. Then sleeps in the playroom all day so we can't access that.
I want her to feel welcome but also feel she is self-fulfilling her belief that she can't be happy where she lives as she isn't even trying to make connections there and just comes back here and lives like a teenager when she is here.
Sorry if any of this sounds harsh. I just feel I need a little breathing space as life is full on and exhausting at the moment.
