I don't think our marriage is working out.?

[cargo3]

I have no idea what to do... We have a house and the kids love this house and their friends.. But spouse makes me miserable.. there is no love, no caring, no emotion, no nothing.. How can I continue this?? The only reason was for the kids but I don't think that's possible anymore. The kids are good except when they hear us argue once in awhile which I think most couples do. But after I dropped the kids off at school today, I just came home and cried. I thought when I married this person 12 years ago that he would be my everything and also keep me at my best. Challenge me, encourage me, learn fron one another, believe in me, love me and mostly respect me. We need to go our separate ways but he says he's not leaving.. What am I supposed to do- rent myself a place for me and the kids? Kids will be sad and confused.. I have no idea what to do and it's a little scary as to me being on my own.. I haven't worked since the kids were born--- he wanted me home to tend to the kids so he wouldn't have to be bothered with daycare or school issues. How does a person get through this? I don't want to be alone the rest of my life. I guess for now I will try and go for a jog to get my mind off of this but I know it won't solve this marriage.
