Why?

Why is it that one day everything can be going absolutely amazing and the next everything feels as though it is falling apart? We were just fine on Thursday. Then all the sudden today he has things he needs to think about and he will call me once he has figured everything out. I understand but at the same time why cant we be adults and talk things through. Isnt that what you are supposed to do when you care about someone. He claims to love me and never want to hurt me but him shutting me out on whats going on is hurting me even more. I want to give him the benefit of the doubt and think everything is going to be ok. But with my track record Im not so sure. Maybe just maybe I am meant to be single forever and ever. I guess only time will tell. But until then I dont feel like eating or even getting out of bed. I just want to sit here and cry. Love you guys
