Age really has nothing to do with it it's the fact that you work so much and with children it's hard to find some one on one time, maybe if you try to do something as a family two nights out of the week that you are home and then maybe three nights out of the week make that for just you and your wife, I think your wife may be tired of being in the house because of you being gone she is the primary care giver to the children and she may just be tired of sitting in the house with nothing to do so that when you come home she wants to do something exciting. She doesn't mean that the marriage is stall she just feels as though life is wasting away by sitting in the house and doing nothing. Maybe instead of dinner and movie or play try taking her away for the weekend just the two of you for the whole weekend at a nice hotel or resort, make it your honeymoon all over again.
I think your wife just wants to feel appreciated and cherished, just the fact that you came here and asked your question shows that you want to make your wife happy and feel loved and appreciated. She may feel that things are stuck in a routine and that routine never changes and she may be getting bored with just being a mother and wife, she may want to feel like she actually matters to you as a person not just the mother of the children. I have included some sites that I found may help you get some ideals of how to make your marriage exciting and not feel so stalled:
