Men, if you're being brutally honest - what thoughtless things have you done that probably upset your SO lately?

In honour of the OP in the valentine's TIFU who I'm pretty sure will be single at some point over the weekend, what do you think you've done recently that was thoughtless and probably upset your SO, even if they didn't say anything?
I've got a good one; my fiancee sat writing wedding invites while I played games a few nights ago. Even though I asked if she needed help and whether it was ok for me to do something else, I'm pretty sure she would have appreciated it if I had volunteered and was simply avoiding conflict by saying everything was fine. I think I ****ed up. Not badly enough for her to be really upset with me, but these things add up, and then we dudes wonder where it all went wrong. I'm going to do a couple more things on the wedding list this week before she asks for help with them, both because I feel very ashamed for dropping the ball on that one, but also because it's the right thing to do because this is our wedding.
So what thoughtless **** have you done lately, and how could you do better?
