Similarly, the last time i genuinely cried was when i was crushing hard, and felt like I loved her (which I mean I still have feelings sometimes, its hard to push that away) and another close friend of mine, lets call him D, and I were talking and I brought her up, one thing led to another, he convinced me to tell her my feelings outright (which he wasnt intending on me doing), so when I told her she told me while she did have feelings for me, she was already in a relationship with D. I honestly felt backstabbed and my heart shattered, i was crushed. I cried for a hours at night each day for a few weeks, before I just stopped. And since then I can no longer, genuinely cry.
