Should I stay or should I go now?

Any opinions would be welcome...my husband of 5 yrs is completely
indifferent to me but we have two beautiful children (19 mos and 3 1/2
yrs) who adore him. I quit work to be with them and have no income.
I'm very depressed to be around him with his lack of feeling/
expression/caring. I think I'm going though the same stages that you
would grieving a death so I'm not too happy but I try to keep up a
happy face for the kids. He's mentioned that he wants to make things
work but doesn't know how to get his old feelings back about me. (Deep
down I can tell there is nothing there on his side). We went to one
marriage counselor session and didn't return for more.
    What would you do if you were me?
