Just that really.
If during a long marriage, one of you goes through something that changes you as a person, how do you adapt to that?
I married very young, been with DH 14 years, i've been to hell and back the last 18mo and at nearly 34 i am no longer the same person i was 14 years ago, and its changing the balance of our relationship and dh is struggling to come to terms with the older, more mature, stronger person that i've grown into.
I thought love on its own would be enough, but i don't know any more.
