Hi there, timsbrat.
No, I can't tell you how to act! I can only tell you the ways I act when this happens here.
Firstly, I think I put a lot of energy into controlling my behaviour so I don't show I am ticked off. This (a) doesn't really work because I 'leak' unhappiness in my body language, etc. and (b) can be pretty exhausting for me.
Secondly, if it goes on for a while, I decide to speak up about what is troubling me. In my head, this is all to be done in a very reasonable, polite and nice fashion. Then I usually try to put it into action. However, at this point my plan tends to come off the rails. I suspect this is because I become hyper-sensitive to any resistance to what I am saying, or the slightest hint that it might not be the best time to say it just now. This is when I start to rant, and I may well feel the need to mention other things which have ticked me off, and which I had been bottling up.
If I am very lucky, my partner can see what is going on, rises above all this, and just punishes me for being disrespectful.
Sadly, the more usual outcome is that we end up having an argument.
So what I am concluding to myself is that I should stop trying to bottle up my feelings, but also accept that it is OK if I complain and my complaint gets rejected or ignored. I don't have to escalate it immediately, the moment that happens.
