I'm being left....

Baby daddy is leaving me after 5 years.... after being honest & loyal for 5 years, holding him down in prison for 2 1/2... & raising our child by myself... I'm getting left ladies. I didn't see this coming! I was completely blindsided... & this person that he has been for the past two days, just isn't him! I've never seen this side of him.. I'm so lost. He says he just can't be with me anymore... he says he still loves me but isn't inlove with me anymore... I'm so heartbroken. This has never happened to me. I don't even know what to think... what step to take next... How to grief... how to move on.. NOTHING! I'm completely clueless.. so I guess why I'm writing this is because... I need major advice. How do I deal? How do I stay positive & strong for my daughter? How do I pick up the pieces? How do I stop thinking about him? How do u stop worrying about him? Help please... I'm rele goin thru it... :( any advice would be so appreciated. Even just having somebody to talk to at this point would. E great.. thanks ladies xoxo
