Trying to impress with home made meals that always go wrong
Using his legs as a hot water bottle when your feet are cold in bed
Borrowing his coat when yours just isn't cutting it
Cups of tea on the sofa whilst watching Celebrity Juice/Homeland/Fresh meat etc etc
Discussing the lives of mutual friends (don't pretend you don't do it!)
Bonding over a mutual love of cats
Do nothing days when we feast like kings and dress like slobs
What else? Trying new things to make each other happy (I go to football games, he goes to the theatre and girly films), getting smug when the cats choose one person over the other, texting each other (funny) insults to try and get a laugh when we're out with friends, making an effort with each others families, shopping for houses and holidays, inside jokes and small kindnesses - things like adding a bunch of roses to the shopping basket, handing over the last biscuit and buying his favourite body wash in Lush because I'm bad at budgeting and he doesn't like spending £8 on shower gel. The list could go on..
