If I'm in a bit of a grump with DF I usually tell him why and see if he knows how to resolve the issue. We have our ongoing little things like him doing the dishes (I get seriously itchy rashes on my hands if I immerse my hands for too long and heat triggers it too so no gloves) or him helping me with things like the weeding but nothing we have big fights about.
The slient treatment doesnt work as DF will come and tickle me or do something absolutely rediculous so I cant help but laugh, sulking fails for the same reasons so I dont bother lol.
DF has told me that he doesn't like it when I sulk and it makes him a bit standoffish so that's another reason why I dont use it as it's not worth it.
So my signature move is probably pretending to sulk, making a joke about it and then popping the serious stuff in amongst the light hearted banter. If something has been building up for a little while then I will have a sit down (or most often lay down) talk with DF and we will share what we are dissatisfied with and how we think things can be improved.
And we haven't had a serious arguement yet
(probably because the moment he gets angry I burst into tears lol. I suck with conflict)
