I think IABU.
We moved here a few years ago and I found a local poker game in a pub. I took DH there and he loved it. It's all middle-aged men (like him) who drink loads of beer (like him) and play poker for a £5 stake. With beer, it's probably a £25-£30 night out.
For some reason, I'm really resentful of it! We don't go out because we're usually skint (I'm freelance and my earnings are feast or famine). But he'll go to this pub night rain or shine.
I'm not setting the world on fire with my own social life which is probably why I'm resentful.
I dunno. It just annoys me when he sails off to it every week, really excited, and leaves me here with the DC. Then in weekends where my ex has the DC, we don't do anything.
It all came out last night and I had a huge go at him. ☹️ He said, "We don't go out because we don't have any money!" But I pointed out that he always finds money for his weekly jaunt. AIBU?
