There was this girl who I loved more than anything in the world. We dated and she said that she wanted to spend the rest of her life with me. About 3 months ago she told me she didn't love me anymore. Of course, I still love her. She's dating someone else now and I tried to kill myself the other day because of her. She's still my best friend, but everything hurts. When will I move on? How do I forget her? Please help.
