Hi wife22, just some thoughts:
If you want to continue with the marriage or see if you want to, then have you both tried talking about what might be "missing" in the marriage, what (specific) things you miss and want back, how to work towards getting them back, what's getting in the way of things being closer between you and how you might break some of that down, the good things in the marriage and how you might build on them, some guidelines about specific things you're both going to do to make things a bit better for each other.
Having said that do you think that maybe you can make some more time just to be "together", doing more things you enjoy together, or even some different things you might enjoy together. Something to bring back that spark? Kind of cut loose from the "here and now" and rediscover things about each other.
Are there other things in your life/lives that might be impacting on the relationship as well, though? e.g. anything with the kids, feeling there isn't "enough" in your life, any dreams/goals that have kind of sat by the wayside?
And maybe it's worth seeing a couples counselor?? What do you think?
But if you find out that you've just grown too far apart after trying to resolve things then you both might find yourself happier with a fresh/new start. There can sometimes come a point where "life's too short" and.....time to move on. Make sure you don't miss that point if it comes.
