She's been married nearly 20yrs, it's always been a volatile relationship but they have both mellowed as they've got older. They have 2 teens and she would never break the marriage up because she doesn't want to spoil things for the kids, although she fantasises about leaving him once the kids are at uni.
She works p/t, her husband earns 6 times what she does. He pays practically all of the bills, she pays for food shopping. There isn't a lot of money left once she's paid for the shopping. She has a credit card bill of £2k which she's slowly paying off herself, her 'D'H knows about her CC bill. They have separate bank accounts; this will never change. She has no access to his accounts, and doesn't even know how much he has in savings, although she knows he received a sizeable inheritance a few years ago.
Her 'D' H has an absorbing hobby and she's just found out he's planning a holiday abroad next year on a birdwatching trip. It's costing £1200 and he'll gone for approx 10 days.
He hasn't told her, someone going on the trip has phoned tonight to speak to her 'D'H (he's working late) hence how she found out.
She is so bloody gutted, feels like he can just do what the hell he wants, when he wants and he will.
She still won't consider leaving though. What can I say to make her see sense?
