My wife and I have been dealing with something like this for a bit now. It's not that our life is bad, but it isn't what we expected. Coming to terms with that and moving forward can be hard. It's not even big things either, it's just the little things.
I often find myself falling into the trap of thinking "life was meant to be different", knowing full well that it is a useless way to think. The only way to really change thoughts though, is to act differently. Life is what it is.
For sure. My wife and I are quite lucky. We might not have a vacation cabin on a lake like we hoped, but we have a camper and a house, and everything we need.
