I feel for you because I am currently going through a seperation right now with my wife and it started with a similar situation like yours. My wife tried coming to me about things she did not like and I paid little to no attention to them. I admit, I was a bad husband and I didnt notice it until she had gone outside the marriage for attention. But I would recommend going to your husband and telling him that you are very very hurt by his lack of sensitivity and you need his assistance as a husband. Let him know that as a husband, he should be there for you, not just financially, but emotionally and also to take care of the kids. Let him know you are very unhappy with his actions and it is starting to effect you. Perhaps that will be a wakeup call to him. Best of luck.
