i don't mean to break your heart anything, but only time will solve this one. that's what others said to me when a relationship was ended harshly and abruptly for me. i was sick of people telling me that, but it's true.
took me eight months to get over it, diagnosed with depression and anxiety, boxed myself in (something i regret), and toughed it out. not the usual scenario for this relationship, but all my friends tell me they're proud of me. honestly, i could care less about what they think, cuz i didn't do it for them, i endured the eight months of emptiness cuz i had no other choice. i changed for the better without even knowing (best friend brought it up and gave me a few days to realize and think about it).
only time will solve it. it still hurts when someone tells me that they had no idea (i didn't tell everyone) and that they're proud of me (even tho it happened almost a year ago) cuz all they're doing is bringing painful memories back and causing me to explain and recreate the whole scene again. wait it out, you'll be okay. just please don't do anything that you'll come to regret while you're getting over it. he did nothing wrong to you, he's obviously a great guy, you should be proud of him.
