Husband doesn't treat me like I'm pregnant

I've always been pretty independent and I think he sees me as a strong person, but it just upsets me so much that I'm doing so much for us and this baby and he doesn't do anything different. He's a great husband and a great man in general, but I'm really struggling and he just doesn't do anything to help besides basic things that we've always done for each other. This is our second baby, our first just turned 1 year old. My husband has always held doors for me, picked things up for me, etc., but he just isn't attentive to me and nothing changes when I'm pregnant.

I'm 8 months pregnant at this point, and physically I am not doing well. It would just be really nice if he would take things off my plate more and check in on me more. We work at the same place, but when we're at work it's like half the time I don't exist. I go to see him and talk to him every once in a while, but he generally does not come to me to see how I'm doing or make sure I'm okay. My mom will notice that I'm not doing well before he ever sees anything. She will say "you need to sit down! You look pale!" She'll get me water and be really attentive to me, but I can't get even a fraction of that from my husband? I've also asked him for months to look up pregnancy massages since he's really into doing research and my muscles are tight and achy. He hasn't done anything other than playing with my hair a little, which he did before pregnancy. This is how my last pregnancy went as well. Basically with me begging him to show more care toward me, make sure I'm okay, etc. and him just shrugging it off. I need more during my pregnancy than him just treating me with basic kindness as he always has.

Everything seems to still be 50/50 (probably more like 70/30 with me doing more chores). We are both working full time and work the exact same job with the exact same hours and pretty much the same pay. I just feel like he should be considering me more and not just expecting everything to be split evenly while I'm going through this. I feel alone and frustrated that I have to ask him to care for me more. Every time I bring it up he gets more defensive. I feel like I'm screaming into the wind. Does anyone have any advice for this?
