So for context DP has always been a total drama queen about the heat IMHO.
OK I get that a lot of people really struggle with it. I don't, personally, I love heat (although today has been bad even for me). But I know people have very different thresholds and I try to be respectful about it.
But DP basically shuts down when its too hot. He has to lie around with a wet towel over him all the time. Can't eat, can't leave the house, can't do anything other than lie in bed. Has to sleep in weird places at night and carries a fan with him everywhere. I'm superficially sympathetic but I actually think at some level that he overdoes it and could reign it in a bit. He's perfectly capable of going to work in it so he can manage outside work. Yes its unpleasant but I don't think its a justification for having to go to bed for three hours like a Victorian woman with consumption when the temperature goes over 20 degrees.
We don't live together but we're together four days out of seven. Our relationship is generally really good, we've been together four years. Absolutely no reason I can think of why anything could be up (obviously you can't know for sure but nothing I'm aware of).
I'm going on holiday tomorrow for five days. He was supposed to come over tonight (as he always does on Saturdays unless we go out) and I was going to cook. I messaged him earlier in the afternoon to ask what he wanted to eat. I didn't hear from him for about four hours and he's just messaged to say he's "too hot" to come over or to eat and will have to lie down in a darkened room until its cooler and then might think about coming later.
I've told him not to bother, I'll see him in a week.
It's always possible there's something up which he hasn't told me but I really don't think so. I think its just another fit of the vapours about the heat and he can't face coming over.
AIBU to think that if your partner is going away you make the bloody effort even if its a bit uncomfortable?
