Unsupportive husband?

Long story short, my husband is supportive in the sense that he works hard both at home and at work, he's a great father but has been quite an unsupportive husband.

I'm a SAHM, I absolutely love it and wouldn't trade it for the world. But I'm human and some days can be really tough, especially the mundane day to day responsibilities, add a fussy, tantruming toddler to the mix and some days can go downhill quick.

If I make any comments about how tough my day was or how tired I am or how I need a break, he immediately gets defensive and goes "well I'm more tired and exhausted, I work and barely get any sleep". Now, I'm very sympathetic and understanding that he has to work which I'm thankful for. It's just the comparison when I complain he has to tell me how much harder he has it.

It makes me feel like my feelings aren't validated at all and that he doesn't respect me enough to be "oh I know honey, some days can be tough, here give me a hug" I never get that response, just a defensive one where he's harder off.

This morning, it was rough, my son was having an off day, tantrum after tantrum. I made a comment to my husband and said "I wish we had some helps on days you work, even just for the company as it can get lonely being alone all day with baby". He proceeded to mock me and say "Haha what help? You need help to put our son down for a nap?" I'm like no...you're missing the point, it's having the extra hands when I'm alone and having another adult here to chat with would be nice. So he said "well reach out to someone then idk what to tell you?" He knows we don't have any family around.

Anyways, I could go on. Sorry for the long rant. I just needed to get this off my chest.

Anyone else dealing with this? What should I do? I've had many conversations with him, too many for it to still be an issue. I think he genuinely just doesn't listen or respect me.
