Is it okay to be a stay at home boyfriend?
What reversed the dynamic with your partner?
My girlfriend is a working woman and she's hardly home.
I'm glad that you are able to comfortably shift around traditional roles, and that your girlfriend is stable enough to care for you a lot. You shouldn't take too much advantage of this though, and you have to pull your weight with house keeping.
She would rather use one of her hundreds of maids to clean my mess and work, than for me to clean.
It sounds like you have quite the ideal scenario with your girlfriend. Since you have so much free time, find some ways to express your appreciation and love for her. Don't get too lazy and be productive while your at home as well.
