Maybe what I'm going to say isn't popular, but this is my honest opinion....
You are married, and I believe marriage is a commitment--for better or for worse. You stated that you love your husband, so if that's the case, you need to do everything you can to save the marriage. I completely agree with those who said to try counseling, even if your husband won't come at first. He might eventually come around. If he were a boyfriend and you didn't feel his affection, then that would be different, but he is your husband.
With that being said, if your husband drinks too much too often and is endangering your children, then you definitely need to get them out of the situation, at least until your husband gets help.
I don't want to appear argumentative (I hate that you can't hear tone of voice over e-mail and message boards!), but I don't buy into the school of thought that God doesn't want us to suffer, so we shouldn't. No, I don't think God's plan intended for anyone to suffer, but He gave us all free will. As a result of that free will, there is sin in the world that has caused us all to suffer at some time. The good news is that His Son also suffered, so He knows what we go through. He can give you strength! I will pray for you and hope you will try prayer, too!
Trust me, I know married life isn't easy, especially when you feel neglected. I've been there. But I think married life has its ups and downs like any relationship and is worth hanging on to...but it won't get better without hard work!
