relationship is successful because of age ,,, still with my first wife (Dominican) she is 40 years younger,,,education we are miles apart... and she wont live in the USA,,,,and there was no financial gain for her,,,,,,well now ever a blind squirrel can find a nut.,,,,,,,Your relationship is successful because (IMO) you’re with someone about your own age, who’s not with you for financial gain. Add in similar educational background and chances for success are even better.
