I think my sister and my parents feel similarly about me and DP! My sister just got back from a massive OS trip and seems embarrassed to talk about it. I've always had less money than her (my choices don't make nearly as much money...you get that with horses and years of uni courses!) and I'm ok with that - I don't worry about what others have or don't have. My mum's always helping us out (she bought this caravan we're living in while DP converts our shed till we can build in a couple of years!). I'm lucky, though, because as much as we're not rolling in money, we are exactly where we want to be (ok, having our strawbale house on the farm NOW would be better ) and it's all part of it for us, and we manage to get what we need, and as Jack Johnson says, everything we need is enough
Meanwhile, all sorts of people end up breaking up - money or no money, it's just at thing.
And ya know what? I'm really happy that you're in such a good place, right where you want to be - only someone looking for misery would begrudge you that!
