What priorities do you need to be aligned to marry someone?

Interest is more important than shared interests, in my opinion. If you're the sort who can't make room in your life for anyone else's passions or are bored by anything that wasn't your idea, you need someone you have a lot in common with. If you can find variety interesting and see exposure to something new as an adventure and just enjoy the fact that your love is passionate about anything, then it matters less so long as you're cool with giving them the time and space to indulge it.

Shared interest is a must for me if I ever get married again. I was married to someone I had very little in common with and it was torture.

Pretty important to have some shared interests. I would also say, even if you don't have an interest in it to support them in it as much as possible.

Must like it in the butt. That’s about it

I gotta say my boyfriend and I don't have much in common but we find each other really interesting, our conversations last hours discussing things. It can be nice sharing different perspectives
