Am I crazy?

Well, here goes......He has been gone for one week.  On one hand it feels like weeks, on the other like he is still here and just upstairs asleep or downstairs "working".  You see even though I am the one who asked him to leave, I am still hurting.  I did not ask him to leave because of someone else, or because I want to find myself, or because I want to start going out.  I asked him to leave because it has been a long time coming.  He was my first love.  He has been with me through everything.  Do I love him?  I will always love him, am I "in love"  with him?  No, and have not been for at least 10 years. I tried to make it work because of the children, and even had another baby to see if that would bring it back....no it did not.  He has not had a steady job since 2003,  he has PTSD.  I have tried so hard to be supportive, to fix him, to help him find himself.  I am now realizing I cannot do it when the person is not willing.  It is not good for my children to see their mom doing it all and their father just existing.  I want him to be a role mode for our children as I am tying to do. I am scared to be without him, I have never been alone before, but that is not a reason to stay.  Now I feel like I need to move on.  I cannot keep doing everything, we were suppose to be partners.  Am I crazy?  I know I am sad, and starting to feel like what am I doing?
