Umm. Be a deal breaker for me. IN fact it was, with my ex. We were engaged but every time I tried to plan the wedding, he was just not interested etc. I came to the conclusion that marriage was never going to happen/not his thing etc, but because it was important to me, our relationship had to end.
I called it off. Very upsetting for both of us at the time but we are still great friends 7 yrs later.
I was stunned (understatement of the year) when he married his new gf this year. Stunned because I believed he didn't 'do' marriage. No. He just didn't want to marry me!!!
Trust me. If she thinks you're the right one, she would marry you in a flash. I know not everyone will agree, but if you're married (or even committed really) then your money should be your money. Really don't understand those who say it's mine etc. That alone would be a huge red flag for me.
