HiSarah - I wrote out this big, good, response and then hit some button and lost everything! Damn Computers. So, I will try and remember what I said.
First of all, I read the two comments before this one and think perhaps one of the mamas didn't understand what your question was. Obviously you are an intelligent woman, and you have made a very hard decision to take some time to figure out your marriage. I hardly think that was a decision that you made in a split second, right? There are a lot of children from seperated or divorced parents who are doing JUST FINE, and who do not have dire consequences from a divorce. (Presidential candidate Obama, came from a single mama, and he seems to be doing just fine) While it's nice to say that reading books, counseling, and giving your husband the validation he feels he needs, works for some people.....for a lot of people that doesn't work. Please do not feel like you are any less of a mother because you,and your husband decided that you needed a seperation. Okay, enough about that....your question was about your kids....
So, now that you and your husband are taking a break (we were on a break!!), you two need to sit down and have a conversation. Figure out the days that you are not working (maybe even talk to your supervisor and try to have the same days off every week if possible) and the days he isn't, and then have them for those 2,3,or 4 days a week. The key is going to be to give them your undevided attention on those days. Take walks, go to a movie, cook/bake, read stories, play games....you know the drill. But I would try to make those days that you have them special. Make sure that you try to do grocery shopping, cleaning, laundry, household chores when they are not there. That way they get mama all to themselves.
Yes, it's going to be difficult. There will be a lot of questions by the older one. I would try to just give her very simple answers. Of course, don't talk bad about there dad, if you get back together you don't want them to think that you had bad thoughts about there dad.
Now, just because you guys are seperated doesn't mean that they wont see their dad. My kids see dad about an hour a day, he works so hard. Your children could probably feel the tension in your house before you two decided to seperate. I'm sorry I keep focusing on that, it just kind of got under my skin, the response you got before. It is never easy to seperate, but your children will be just fine as long as you and your husband to a great job of letting them both know that you guys love them. Good luck, L.
Okay, sorry, I just read that guy, Rosemond, online that someone recommended, and I think he is as much of a quack as any other doctor or pychologist. I don't know if you are a bible-thumpin' christian, but he is, and I have a feeling that if you read it you will just think that you are a failure as a wife and a mother, and that's really not going to help you out at all...is it? There are tons of counselors that you can talk to, who do NOT take sides, and I am sure they can help you, if you feel like you need it. Sorry, it is still gettin' under my skin!! Good Luck
Also, there was this thing, a joke, going around on the internet, email, whatever, that was published in old home-ec books about the proper way to care for your husbamd. "Don't talk about your day" "make sure the kids are bathed and quiet when dad gets home" "always make a home cooked meal" "get yourself gussied up for him when he comes home" "Have a hot meal always ready for him" DOn't complain, he doesn't want to hear it"...BLAH BLAH BLAH....you can't control your husband any more than you can control a donkey. He decides how to feel, what to feel, and when to feel it, whether or not you rub his feet, great him with a hug, or get down on all 4's and bark like a dog. My husband would not love and respect me if I bowed to his every whim, and he would think I was high if everytime he came home I threw myself into his arms to welcome him home....OKAY, I will write nothing else....Good night
