Unspoken rules

In a relationship there are a lot of spoken rules, but as well as rules that are not spoken of until the time comes to talk about them. Such as not eating my food that I left in refrigerator obviously I was going to come back for it later, how about do not take my last cigar or cigarette and not say something about it. Little things grind your gears in relationships, especially when you expect your partner to know better, and you do not do those things to them. I understand we are a couple, but there are boundaries between us just like in any other relationship or friendship that you have. You still should ask before taking my things, because we both know how aggravating it is to wake up or come home looking for something you totally knew was there where you left it. Just a bit of a vent here at two in the morning ahaha…. My boyfriend works at night so when he is off and home sometimes he wakes up around this time huffing and puffing (like a little girl around the house) which wakes me up grinding my gears of course. I hate it but I love him so I tolerate it! Anybody in a relationship or friendship where the other person does the littlest things that piss you off? Share with me please, it`s healthy to talk about it.
