La Douleur Exquise

"La Douleur Exquise - the exquisite pain of wanting someone that you know you can never have, and knowing that you will still try to be with them." It's bad enough that she has someone else in her life. She was happy, and who was he to ruin that? But he wished he could the one for her. Instead of him. Follows First Class then Days of Future Past. Charles/OC/OC, some Raven/OC.
