a little bit of context me and my friend we’ll call him Mark as to not give out to much info have been friends since we where both 5 years old our parents owned a business in France together. when we both turned 7 we moved to the us together and have grown up together since then i now F19 and him M18 have been friends forever. however marks dad was never the best to him he often drank a lot and would do horrible things to him. ive always been here for him through everything id often be the one looking after him when he was hurt physically and mentally hes like my brother and id do anything to help him. Mark has been in therapy since he was around 11 when he turned 16 he was diagnosed with DID but refuses to accept or even talk about it. he wont get help or even try to work with any of the info he’s given hes been diagnosed by 3 different professionals yet still believes he was misdiagnosed by all 3. recently ive noticed him more dissociative and desided to dm his boyfriend at fist it was a normal conversation about him and things we both showed interest in eventually when we where on the topic of how well mark was doing in therapy i just out right said "you know he has DID right?" knowing almost full well he didnt… luckily his boyfriend had thought he had something like this but never wanted to push him we talked a bit on how he dosnt think he has it a refuses treatment and by the end of it boyfriend agreed to talk with mark about maybe giving it a try. that next day i woke up to several angry texts from mark going on about how it wasn’t my business and i had no right telling his boyfriend about something "he dosnt even have" though after i apologized and tried to start a conversation i was left on seen his boyfriend had texted me telling me how mark had agreed to going to therapy and actually trying. that was a few months ago. now mark is at peace with his diagnoses and owns it. he got treatment and is doing so much better now. we dont talk much anymore other then the occasional how are you witch is almost always initiated by me though the conversation always dies after a few minutes… i cant help but want my best friend back i understand maybe i shouldn’t have just told his boyfriend like that but i cant stand see him suffering knowing he can get help. and now that i have i dont have many regrets as hes happier now and struggling less and less with every day. im not to sure what to do now but i cant help but wonder… Am i the asshole?
