It really gets my goat when people dismiss what I'm saying with an airy you'll never do that/ you won't do it.
Latest example, and I know this is completely petty, I was sitting in the living room saying to DP that I was really pleased with how I'd arranged our Christmas trees/ decs this year and was going to take some photos so next year I could have that as a reminder to do it the same way. Oh you'll never do that was his response.
I found this massively irritating and told him so. He then said oh well I shouldn't say anything/ pardon me for speaking which is his default whenever I don't automatically agree with what he says.
I tried to explain why this annoys me, I've had a lot of people over the years tell me I won't or can't do things. Worst one was when I was in an abusive, shitty relationship years ago and my then closest friends, when I used to talk about how unhappy I was and was desperate to get out (but was financially trapped), used to say you'll never leave him. I did leave, no thanks to my friends though.
DP just doesn't get it, and just went down the he was only making a comment because I WON'T do it, and I'm the one being unreasonable.
So am I?
