I built a house on her family land ( not a luxury one). I pay for all what are needed for daily life. She pays for all unrelated, even for her personal things. Hotels and restaurants are on me. She owned 2 Japanese restaurants in past, but she is retired now, just like me. We help each other if anyone of us needs help about something (not financially). A few months ago she spent 2 weeks at a hospital and I was with her almost all the time (only went home to get some asleep, out of home 4:30am, back home 4:00pm, sometimes 6:00pm.
No daily, monthly, or annual salary. It's something close to a western relationship.
We are not together for money, not me, not her.
