Everyone has a different life. If you weren't swamped with six kids, you'd be swamped with something else.
I have been married for 13 years. I married
DH when I was 20. Didn't go to college. DH has two kids. They are basically grown now. I went through all the crap that goes along with having stepkids. I have a house, two cars, a good job, and am in debt up to my ears. We don't have kids together but are trying now. I'm happy.
I recently got together with a friend I knew in school. He is my age. When we graduated from HS, he went to Yale. Studied music. He had a girlfriend for five years, but she wanted to get married and he didn't, so they broke up. Then he lived in Seattle for a few years. Dated a few more girls. He met one girl from South Africa and dated her for a while. He then moved to South Africa for a year and lived with her. He recently came back and is trying to move to California. His girlfriend should also be coming back to the States soon.
He has no job, no car, no place to stay. But, I think he's happy.
At work, I'm in the process of watching two of my co-workers go through divorces after having kids. They were both married for a couple of years, had kids, and are now splitting up. In both cases, I think it was because they didn't get a chance to do what they wanted to do before the kids came along. I think one spouse in each case was pretty immature and wasn't ready for kids.
I think you are mature enough for it. I think you'll do just fine.
I guess the main theme (??) of my post is to say that even if you had different responsiblities, it might not make you any happier, better, etc. Wouldn't it be fun to just drop it all for two weeks and go party? Some of us have that option, but some of us don't. But if you don't, it's not a bad thing.
It's hard when your hubby is gone for weeks/months at a time. I think the stress you're under is why you posted, not that you are dealing with six kids. If your hubby were there, you probably wouldn't have posted! You just need a little break, and you'll get that once your DH gets home.
You're doing great, hang in there!!!!
