Re: My wife feels like she wants to be on her own
I'm 31, married, stay at home mom w/3 kids. And, I too have talked to my husband about potentially going out on my own for a while. You're question was how to try and keep her. I'll stay on track with that, but real quick note to some of the other posters: just because someone wants to spend time by themselves, does not make them a terrible person or an adulterous spouse. There are many other reasons a person feels this way.
I've done a lot of soul searching to figure out why I've wanted to leave...leave it all behind. Kids, house, security, etc... My husband IS a good man, and he IS trying. All that being said, I still sometimes want to leave. Why? I finally figured it out: I married too young. I never experienced life on my own. I went straight from my parent's care, to my husband's care. I firmly believe that if I had spent time alone to face the world, I would have had time to learn more about who I was, why I do the things I do, learn more about my passions, find hobbies, etc... But as life went: I always worked FT since I was 17. In college I worked 60 hr weeks on top of school. Then I dived right into marriage (with work), then 3 kids. I've never had TIME to see who I was. So, no other man in my sight: I wanted to know ME. And I feel like I can't do it with everything constantly buzzing around me. It's all chores, toilet scrubbing, snotty noses (bless thier little souls),....
How to keep her? How to get her to stay? You leave. Take the kids. Not in a bad way. I mean, let her have her home in peace & quiet without having to worry about everyone, listenting to the kids screaming for her, not having to be confined to 1 room in the house just to have thoughts to herself. I suggest you start taking the kids to McDonalds when you get home. Take them to train shows (or whatever) on weekends. Give your wife time alone in her own home. Also, suggest that she finds something she loves to do, and find a PT job doing it. Tell her you'll adjust your work schedule so she can have a life too.
Anyway, that's just what I wish my husband would do. Even as I type this, I've been interupted about 60 times by a 3 year old who won't let me think, and I have to start a carpool now. I never have time to do anything on my own. And that makes me want to be on my own. I don't want to give up my marraige or leave my kids...but I do need to be ME again. And it feels like the only way I can have ME, is if I leave everyone else. Don't make her leave you to be alone with herself. Take the kids to a movie every night or something. She'll fall in love with her home again.
