Compromises you've made for partners and how they turned out.

I have a lot of friends in marriages/ltr and it seems like someone is always compromising on something they originally thought they were looking for. You often hear "not who I was looking for, but who ended up being perfect for me" or similar lines. I'm not encouraging lowering standards, but I think we've all experienced shifting priorities for partners. What are some "musts" that you became flexible on and how did that turn out? What are some "nevers" you became flexible about and how did those turn out? Your experience might not help everyone, but it could provide insight to others.

Some personal examples: Must: like reading I had a long relationship with someone who basically never read anything. I still had friends I could talk to about books, and they spent their time building things. I realized it's a nice plus, but not a necessary part of a relationship for me.

Never: workaholic I had a year long relationship with a workaholic. They tried so hard to back off from work, and I knew I was important to them, but so was their job. I ended things after a year because of this. Still a never again, but I'm taken now so hopefully it won't matter going forward.
