I feel like my husband is gaslighting me

So earlier today my husband and I were arguing because he just came in from laying mulch all around our property in 90 degree heat (definitely not something I told him nor would ever suggest he do) but he does things outside in all weather’s regardless of what i say, its always been how he operates. When he came in I mentioned being frustrated that we hadn’t worked on getting a patio set up or fixing our deck and walkway as our deck and walkway are made of old wood and its rotting and become dangerous and attracting termites. I really was in no way was trying to crack the whip or expecting him to do it alone or start this summer but he immediately took this as a hit to his ego and saw it as me being ungrateful for everything hes done so far (he spread mulch, we got a new shed and through insurance we got our roof replaced which is great but its not like he installed the roof himself and the shed was a small and rather simple to assemble and the mulch is part of outdoor maintaince and i sure as hell didnt expect him to lay it by himself in this heat.) He started getting defensive saying he had been outside all day several days in a row laying mulch by himself and I told him that that was his choice and I never asked him to do it nor did i expected him to do it by himself in the heat and i didnt participate not because i didnt want to help but because it was simply too much for me. Because he emphasized how he did it by himself i commented and said as someone who immigrated from England, i’m not use to the extreme heat nor do I ever think I will be and I have no desire to do strenuous landscaping in 90 degree heat as I don’t think its safe and he immediately said I could adapt to the heat and that I just didnt want to. I bought up risks of heat stroke, reoccurring health issues I’ve experienced do to the extreme humidity since moving out here and it still isn’t enough for him. I asked my mother’s take on it in whether she thought I was being unreasonable not wanting to do landscaping in 90 degree weather and she said absolutely not. When I told my husband he accused me of lying and saying I never said you had to be out there with me. This is what confuses me as he more or less just enphasized working alone while having a go at me and said I could adapt to heat if I wanted to. No he didnt say the exact words you should be out there with me but he clearly implied it but im apparently a liar for taking it that way. I can see how some people might think im being too demanding with the work I’d like to get done (after the summer heat, me helping not just on him) but regardless there have been many incidences where my husband will imply something or make me feel a certain way then completely deny it when hes called out and it leaves me feeling crazy like I dont know if i’m right or wrong or just going crazy. If you had the paitence to read through this thank you and please tell me what you honestly think even if its that I’m an entitled B…
