I'm completely in love, more than ever before. I really feel like I've found someone who truly completes me. He felt the same way for a while, but then started to pull away. Now he says he doesn't feel he can commit to me the way I need him to, and he left me.nI've never been so sad a* felt so alone. I am afraid I'll never find this kind of love again. How can I pick up the pieces?
