Just because you're a couple, it doesn't mean you're in charge of each other's happiness.
In an era where making ourselves happy is hard enough, how could you make another person happy?
Do not promise each other more than you could attain for yourself.
The only thing you could really promise is to allow them to become whomever they want to be, since not being a hindrance to the other is the best thing you can do for your partner.
