First, I'm so sorry you are struggling in this way. Marriage is supposed to be a 100%/100% partnership and with kids thrown into the mix, I know that can put a strain on a marriage. It sounds like you are doing a great job so far...keep it up!
My husband and I have been married going on 5 years, so I feel somewhat silly offering advice to you, but here's my two cents anyway!
The marriage vows you took said "for better or for worse", not "as long as the for better is more often than for worse". I agree with several of the other women that you are sticking with it, getting outside help, which is WONDERFUL! In our day and age of "no fault" divorces, fighting for a family is rare!
I should tell you (and I'm not trying to brag, so please read on and I'll explain more) that my husband and I have an awesome marriage, now! Neither of us is perfect, so what helped us get past that first HORRIBLE year of fighting ALL THE TIME (and we didn't even have kids yet!)...we discovered and instituted "The Five Love Language" philosophy, among other things like not going to bed angry (no matter how long it took, we talked or fumed on the couch and MOST times, the later it got, the sillier or the pettier the arguement seemed...yes, I'll admit a few times where we admitted defeat and agreed to go to sleep and talk more the next day, but we scheduled a time to talk), I talked with him about what bugged him about the house and told him about how tired I was with working and now with the baby and that I would rather focus on family time during the week when I came home and that I would do house cleaning when the weekend came. He seemed to understand that and was happy that I saw and expressed that he was more important to me than a clean house. I also told him that if something was bugging him, then he could either ask me nicely to do it before the weekend or do it himself and now he doesn't mind that the dishes pile up until the weekend or that sometimes I go two weeks without doing laundry and even will nicely let me know when he is running low on something as a kind hint to get it done sooner rather than later.
Anyway, back to my previous point, The Five Love Languages is a book by a Christian author, but I so believe it is pertintent to anyone and every one regardless of beliefs. It states that everyone can generally be catorgorized into five love languages (Acts of Service, Quality Time, Physical Touch (like hugs, kisses, touches on the leg, etc), Words of Affirmation and Gifts). We usually have a primary and a secondary love language and this is how we fill up our love tank which takes effort on our spouse's behalf to fill it up and keep it filled.
For example, my primary love language is physical touch, so if my husband is not hugging and kissing me or coming up behind me and touching my back or things like that, my love tank starts to empty and I start to feel depressed and worthless, but if he is doing those things, I feel that I can focus on his needs more too. My secondary is Words of Affirmation, which means I crave compliments. After doing this for awhile, I find I can tell my husband when I feel my "tank" getting low and he makes sure to give me lots of extra hugs and touches that night or compliments me lots (sincere compliments). In turn, his love languages are quality time (primary) and gifts (secondary) which means he wants me to spend good time with him each day and I lots of time will surprise him with a gift when I go to the store or I get the house work done early, things like that. So I have to make a 100% effort to keep him full and he has to make a 100% effort to keep me full. When we are both full, we discovered that we fought less, were able to talk rationally more and the home life is much nicer. We still fight some, but it seems the fights are easier to resolve and much fewer!!! If you are interested in this, you can find the book on Amazon for relatively cheap or lots of churches do this program and you could call around and see who is doing it (you don't have to be going to their church to take advantage of this book, I wouldn't think...I know in my church, we'd welcome you in!!!). Anyway, the author is Gary Chapman and I would highly suggest even just taking a peak at it...what can it hurt (can you tell that I am now a HUGE advocate of this :oP )?
Also, make an effort to plan special date nights with your husband. Leave the kids with family if you have them in town or find another couple that you could trade off with (for free babysitting for both of you...what could be better!!!) Anyway, that can mean so much to your husband and it gets you two away from the kids for a few hours so you can have grown up adult conversation together.
I also agree with some of the other women when they said pick your battles. It's easy when we get angry to just to continue to nitpick about everything!!!
Sorry this got so long!
Well, good luck and if you need to talk anymore or want more information about the "Five Love Languages" (it works for your kids too!!!) I would be happy to help (my husband and I have now had the pleasure of teaching this class as well as our personal story) or at least let me know how things are going! ____@____.com
