I've been with DH for 18 years and I'm going through a big questioning phase. He's a lovely guy but we've had our ups and downs over the years and I feel like we've grown and changed in different directions. When I look ahead and think about when our children leave home I wonder how much we'll have in common once the shared task of parenting is (mostly) over.
But maybe most people feel like this and I should dig deep and work on our marriage?
I don't have any other marriages or long term serious relationships to compare to (had a lot of short term flings before eventually finding DH). What does a good marriage feel like? Should the person be your best friend or am I idealising marriage by thinking that?
