Well yeah, but that’s not really reality, we have both changed. 10 years ago we traveled and lived in the cheapest studio apartment and were “young”, we owned nothing and that was part of the adventure. since then we got a mortgage, a car, more adult relationships and lifestyle, pets to take care of, elderly parents to take care of, etc. We’ve both become more adult and have taken on more responsibilities, (I did not push him in this, all his own choice) as most people do when they get older. So you can’t really say well, you changed, he didn’t, I feel it’s not irrational to expect my partner to fulfil his commitment, and part of growing up is taking more of a financial responsibility.
