Any advice will help!!

Ok so I just started a new job...I've been a stay at home mother for the past 8 years...I don't mind it but wanted to help with bringing in some extra money for Christmas.

Before I started working last week, the ol man started accusing me of cheating on him...I've never thought of doing so, and it REALLY hurt.

The first night at work, I go in frustrated because I was not only nervous about the new job, but REALLY upset about being accused of cheating on him. When I get off, I find out that he was going through my friends list on facebook and picked my newest friend and said "I hope he's ready for you..."

My girlfriend, who always has my back, sent me pics of the conversation that the ol man and her had...saying he's gonna have my text history sent to him at work just to prove that I've been nothing but a cheating hoe...and when I get home from work that night, being tired as all get out, he continues to accuse me of fucking around on him.

Knowing I not only have to go to work the next night, but I also have to get up to get our kids ready for school, the ol man keeps me up till 3 in the morning...so not only do I wake up late to get the kids ready for school, but I end up having to stay up ALL day cause I'm the only one here to take care of our son...

Later in the week, he starts acting like he sick (which he does when he gets really stressed about anything) and actually starts running a 103 fever...

So now the only way to get him "well" again is to suck up to him and make him feel like he's the MOST IMPORTANT THING IN THE WORLD!!!!

And with him "not feeling good" my kids have literally destroyed the house, which means that instead of being able to nap during the day, I'm stuck cleaning the house as if I didn't have a job, and instead of enforcing my rules and making the kids do their nightly chores, he doesn't do anything to help out!!!! He fusses that the kids don't listen to him, that he's tired from work, and that he's the only one wrapping any of the gifts that were bought for Christmas...it's like no matter how hard I try, I can't win!!!! I've even thought about leaving him because he acts worse like a baby then my son!!!!!

Now he's saying I'm gonna have to quit because the house isn't in order, he's gonna have to be working 12 hour shifts, and he doesn't like that we're working opposite shifts!!!! I feel like I'm stuck between a rock and a hard place!!!
