married & taken advantage

ashbash4 • Mommy to Carl and Cora; LOVE THE LIFE YOU LIVE; fuck what anyone says
I've been with my husband for 6 years now (2 of those married) and I just became a stay at home mom for our first baby.. I love being able to stay home with him and do all of our house chores. But lately I have really started to feel like I'm taking advantage of my husband. I don't feel thankful for him paying all our bills, paying for my car, working 8-9 hours a day, etc. I used to always feel so thankful & happy and now I'm just like blah about it. It's hard to explain.. I keep having this "I'm a super mom" mentality..do any other wives feel like this ?
Do you think I could just be missing my job & helping pay the bills?
