See what you can find out before you go to the stage of moving in together.. That would be my thought on it at least..
So gain more beforehand and see how she reacts... It might start the conversation you need to have.

Go for it!! Literally pig out non stop and see what damage you can do.. Even dropping a gym session a couple of times just to make the overall gains more noticeable (because you can double up on the gym after the 4 weeks).

Definitely need to let me know how it goes.. And interested in what sort of gains you make too.

I dropped you a message with a heap of info.. Happy to expand on that list too..
