When will the pain end

A day has come through and I survived it, but it still hurts. The thing that flows through me is that she said I loved her too much. That giving 130 % was too much, that she would never love me 100 %. The idea that someone can say they love me, and love others, won't give 100 %. How can I trust again? How can I not? I have more questions than answers and not many to talk to. I feel like an island, so I tell myself how an island is strong. No matter how small, the water never swallows it forever. I know the pain I have in my heart will stop. I have to grieve the death of my love for her. I have to weep to get it all out. I need to feel the disappointment. Most of all, I have to be above it all. I can not get vengeful, won't solve anything. I have to in the end, be too good for her. I did not give too much, I was too good for her. I do believe it, yet the pain is because I did love her so much. So, when will the pain end?
