Every morning at 8am.
Him "morning Hun, love you xxx"
Me " morning Cunt, xxx"
Is it bad that all I have to press is the m and my phone knows what I'm gong to say next and adds "orning cunt xxx" for me? 
Sometimes if he's doing the driving he doesn't get to text me so I'll send him one saying "oi cunt xx"
Every now and then he will send one on an afternoon
"What you doing? Xx" if I'm bored I'll say "the milkman" or something daft.
When I had breast lump removed and going through paperwork with nurse before hand, she took dhs name etc, then asked if it's ok to access mobile in my bag to contact him if needed, (was already in locker so I couldnt get to to it) had to bullshit and say I didn't have his number saved so gave it to her to write down, all my family are saved under daft names and Dh used to be saved under cunt.
I love dh and don't think he's actually a cunt. It's a joke that stuck with us, step brother once left nasty messages to me after dad died in which he gave everyone of my family a nasty name which we all adopted as pet names for each other rather than let him upset me. Didn't fancy the nurse scrolling through my phone wondering why "arselicker" "bald bastard" and "cunt" where the top three contacts in my phone...
