Asked partner if he wanted to go into the nearest big city for a cheap casual lunch and a few drinks this weekend as nice weather. For context we have not been out for a meal in 3 months since we came back from a weekend away (1st holiday together in 4 years). We both have well paid jobs (+£100k a year between us), the house is currently a drain on money but he does have other hobbies he spends a chunk of money on monthly.
He said that he doesn't have any money and is now storming about and in a huff that I asked. We never go out unless it's for a walk and maybe a drink at the local pub now and then. I feel we don't have any "new" experiences now and I'm bloody bored. He also wouldn't be happy if I said I'm off out with someone else instead. Our weekend days are all about house to do list and walking the dog - I feel unreasonable to expect to have a proper day off life admin and work. I only want to go out with him once a month or so, AIBU?
