James was only with you because you were so sad that he felt bad you were never going to have anyone true who would actually love you. Harry was only using you to make himself feel better, it gave him a little confidence boost every time you were nice and loving. He was probably cheating on you in all honestly. Luke... Luke is messed up. You shouldn't have gotten in with him. It's only going to cause you pain and turmoil. He hates himself and he hates you now as well.
"No! Stop it, alright! Stop saying such terrible things about James! He loves me, and I love him! It wasn't pity!"
"Harry would never do that, alright? He was just as loving and caring as I was to him, maybe even more! So stop saying these wrong and shitty things!"
"No matter how broken or sad Luke is, I'll always love him! And if he hates me, thats alright. It'll pain me for a long, long time, but I'll never forget that what we had together was amazing."
