I'm going to go ahead and throw this out there.
I absolutely, positively do not mean to be offensive in any way whatsoever, but it sounds like you might have an abusive husband. You don't have to be hit or physically attacked to be abused.
Based upon the information you've given us, it sounds like he is using your situation and your 'traditional role as a woman' to perhaps control you and keep you in the house. You mention that he denies you time for yourself because it "went out the window when you had kids". That could be a form of controlling behavior. You mention that you can never do anything without having to 'ask' first. That could be another sign of controlling behavior. You mention that having someone else to watch them is out of the question - I'm curious as to why that is. Is it because you don't trust someone else watching your children (which, I totally get that!) or is it because he is opposed to you finding a babysitter or frowns upon you hiring a babysitter because it means that you get to get out of the house and have time for yourself. If it is the latter, that could be another sign of controlling behavior. You mention you feel guilty taking time for yourself when your husband gets home because you haven't seen him all day - does he ever make you feel that way? If so, that could be another sign of controlling behavior.
Again, I could completely be reading this wrong but with the information you've provided there are definitely some potential red flags. As far as your situation is concerned, put the kids to bed when they are tired. Period. Keeping them up to see Dad is disruptive to the sleep they so desperately need for proper growth and development. Additionally, good sleep at night will translate into better behavior/disposition (not saying they're not well-behaved, but lack of sleep can lead to crankiness and discontent), which will translate into potentially calmer, more peaceful days with you.
Have you ever heard the saying "If mama ain't happy, then NO ONE is happy"? It's so true. Your husband takes time away from his job AND his family to be with his buddies or go hunting, and he does so because it is a way for him to unwind from his daily grind. You are entitled to a break too. Instead of 'asking' your husband to watch the kids, 'tell' him: "On Saturday afternoon I am meeting up with my friends for coffee at Starbucks. You will need to be available to watch the kids." With some men, you just have to be blunt and direct. If he tells you "no you are not allowed to be with your friends", then you may need to take a serious look at your relationship.
Trust me, I don't mean to be harsh and your situation might just be a simple case of the 'man not getting it' (who of us hasn't experienced this?!?). Please do look for red flags though if your husband is 'isolating' you, because although that sort of behavior doesn't leave a bruise or a mark it is still abusive.
Best wishes to you.
