I Just don't Know :/

I would like a little sign that every thing happened over the last day would go away and be okay..but I don't see that happening. It's not like I want this I really don't but what is a girl supposed to do when the person she put every thing into..makes it so easy to leave, for him and not me. He can hand back every thing that I have ever given him like it was nothing. Was it nothing? I don't  know. I just don't even know what to do anymore. It just feels like it was all for nothing now. After every thing that I thought we were working for it's basically falling apart. There is no way i could have taken that a different way last night. It's not just me that thought that it was a cruel and heartless thing to do. If he wants it to be over..do I just let him leave..or keep fighting for something that just won't seem to stay...happy?
