Am I making something out of nothing 🤦🏻‍♀️

Soooo me and hubby been together 8 years have children together... he works 8-5 and I picked up some work in evenings to help with some bills and stuff. Anyway my in laws said they’ll help with kids as much as they can coz I have to leave before my husband actually get home. So it’s literally not for long I need someone to watch my kids. Anyway a couple weeks into the job they turn around and said they need notice I just can’t expect them to have the kids. Bearing in mind it’s been mainly my family helping me out, they’ve had them about 3-4 times for me 🙄 so I thought I won’t even bother asking them in future I’ll just rely on my family to help out. Keeping in mind that there is ALWAYS someone at in laws house. As his brother, wife and kids all live there. And she doesn’t work. So she’ll literally have them for like 10 mins till mother in law gets home from work 🤷🏻‍♀️ but it’s always been like this they would go weeks without seeing our kids if we didn’t take them over there to see them. They always go out and do things with their kids but never offer to take ours with them. Not even ask to have them a couple hours over the weekend so we get a break. It’s literally always my family that will take them out for a day so we can have some time alone etc. Husband thinks I’m over reacting and basically always has a go at me whenever I mention anything about it 😤 and causes a huge argument every time! Just really starting to pissss me off! I’m pissed off he always sticks up for them. Pissed my kids always comes second best! 😡😒 and she doesn’t work every day of the week either so while I’m home all day with my kids trying to keep sane keep house clean and get ready for work. She doesn’t even offer to take them off my hand or anything and have them for a bit during the day 😐 and when i have taken them over there to head to work I left literally like 45mins early so I stopped for chat and stuff. Then next thing I know when I’m at work husband calls asking me why I dropped them off at 3 instead of 20 to 4🤷🏻‍♀️ like was they moaning to him I took them their a little bit early 🤦🏻‍♀️😤 like seriously what is wrong with all these people!! 😡😡
