I read your posts, you said she sounded unhappy and you were sorry which is not an apology at allan extremely backhanded apology. You continued on after it with more smugness about your marriage and compromise as though it is objectively rather than subjectively required. However you haven't once asked her why it is she feels unhappy. I am happy because i have compromised ergo she must be unhappy because is not compromising enough how irresponsible that she won't keep her family together is how it comes across.
"One" is not required to compromise, nor is "one" required to remain in a relationship or a marriage which makes "one" unhappy or even in a relationship at all. Staying married does not mean a relationship is of good quality, a good quality relationship can occur without compromise if the partners involved have the same values, equally compromise is something that is involved in most people's relationships because people differ from each other, all of that stuff about compromise being necessary can also be really damaging to relationships.
Compromise, however, is not the same as priorities changing when something unexpected happens; a husband or wife cancelling a hobby to look after a sick partner/child is therefore not a compromise unless it is negotiated unwillingly, it is simply a change in priorities based on an unexpected event. If it has to be a compromise that's not really a great relationship because one is a need and one is a hobby.
A compromise over holidays might be going somewhere that ticks boxes for both but suits neither fully or taking turns, going to the other's or the children's favourite place because democracy rules is a sacrifice not a compromise. I'd think it weird if a parent felt a child-oriented holiday was a significant sacrifice.
That is why it is really unhelpful and mean to just announce to someone that "marriage is about compromise" and you are irresponsible if you don't do it, because that is simply your own choice about how you conduct your relationship and because you haven't asked anything about the op to know that's the problem. I think it is highly unlikely that anyone would be unhappy because they weren't compromising enough, people dont have to compromise or be made to compromise if they don't want to and people either want to compromise or they don't, they want to sacrifice or they don't and more often than not people are stressed and unhappy by too much compromise/sacrifice because that just indicates benignly; incompatibility or malignantly; some abuse.
It therefore comes across as staying together is the most important thing to you and based on your descriptions of your relationship on this thread - women have to suck it up for the sake of keeping their man and that this is the objective truth of good relationships rather than simply your personal view.
Your relationship may well be more equal than how you have described on this thread but I find it interesting that the compromises you mention you making are about taking on entire responsibilities because your dh doesn't fancy them and reciprocally your dh looking after his own dc when you were studying/cancelling a hobby when you were sick/him being ok about helping with the house when it is an emergency.... Not particularly equal examples because they convey that in order to be let off a shared responsibility, even one that he has passed completely to you, you need to have an important reason, whereas he just doesn't fancy stuff.... And this is ok because he told you what you could expect before you married and you were happy with it. It is more about attitude than anything, it sounds as though although he considers himself superior you also consider him superior and therefore you are both happy with an arrangement where he is in practice superior. That's the impression I have got from the way you describe your relationship.
