Pitfalls? Advice? It'll just work out if its going to and it just wont otherwise. Also have a lot of sex, that seems to help.
I got scarily domestic when I moved in with my boyfriend. I had never cooked or cleaned in my life but I like baking and cooking for him and I like to keep the house (relatively

) clean. He cooks and cleans up a lot too, so there's not much stress about it.
Let the lady dictate the cleaning and do it.
She will reward you with cakes and intercourse.
For the record we never talked about anything beforehand or set up "groundrules" lol. Our conversation went like: UH WANNA MOVE IN TOGETHER? UH OK COOL
Its really not too hard to cohabitate with someone you really love
Jam it back in, in the dark.
