Do foreign brides make the best spouses?

I am always wondering if foreign brides are the best spouses. I have been dating women and just like me, they just wanted to play around. They want to have fun and I don't want that anymore. I need a wife-material woman. I am not getting any younger and I need a spouse who would actually stay with me until my hair turns white. I got friends who told me that mail-order brides are trustworthy. Do you agree with this?
