Advice much appreciated... in Life Lessons

I’m really struggling here… my mother in law and sister in law hates me and they make it obvious.. sil is dumber than a box of rocks (can’t do basic math in her head, can’t read well or spell) my mil seems to be financially incompetent (always trying to convince me and my husband to spend large amounts of money or open multiple credit cards) they both work at a tax office and recently had to give mother in law my financial information that should not have been needed for taxes…
I’ve also been having baby fever pretty bad although we don’t want to have a kid for a while..
I’ve recently gained quite a bit of weight and can’t seem to get it off..
I’ve been having major health problems lately and we are unsure of the cause…
I tried talking to my husband about all my concerns and tried to explain that maybe a vacation could help the baby fever, and I’ve told him a few places I want to go to (been mentioning these places for 2 years now) and suddenly when I mention these places here acts like he had no idea I wanted to go.. because he is always playing on his phone and not listening fully.
I’ve been an emotional train wreck and crying a lot. When I’m upset and crying he just tells me how horrible he is and makes me straighten myself up to console him..
he also had his mind set on building a race car (something I have no interest in) and tells me we can’t go do things because I need to focus on saving money…
I tried to tell him that life is hard for me and that I’ve been struggling and he just says I’m fine.

Sorry for the dump but I just really need some help..
