Anyone go through this? Is this temporary?

Hubby isn't trying anymore...he doesn't kiss me, rarely cuddles me, I have to nag to get his attention. After baby girl was born he's become entirely different, careless, distant. I don't know what to think...I've talked to my big brother and I suppose, since hubby hasn't even tried anymore, the words "I still like him" fell out of my mouth as I was venting. My brother stated I should find a job and do what I can to make a better life for her. He said it's just her and I now. Hearing that...makes it worse. I can't leave him. We've been through a lot, we have a baby together. I love him don't get me wrong...But lately seeing him not loving me like he usually does...makes it feel as if I only like him enough to tolerate his lack of trying. And I know it sounds bad...But I can't help hoping things will be as it was before. All I can do is hope..
