Why would a man think his wife or gf loves him?

Other than the extremely rare cases where the below does not apply? I never understood how it is that most women 'love' and no one has been able to explain it. When in 9 out of 10 cases, she would not 'love' him if he had no job or was incapable of making money. Generally she won't even love you if you have money but don't spend it on her ie. won't pay for her dinner, movie, etc. Clearly if a woman approached you and said "I'll love you but only IF you own ______ and make atleast _______ a year", you would not think it was real love, well they may not tell you that but this is the case. So other than the extremely rare cases where the above does not apply, how do women love men in romantic relationships?
