hi. i'm 19, my ex is 20. we briefly dated for a couple of months first year of university, so an extremely short amount of time. it was both of our first relationships, but i had experience with guys before, meanwhile in the past all his crushes were unrequited. he randomly broke up with me 4 months ago and there had been no contact for 3 months.
i've moved on now but recently he's spiralled out of control - writing daily fanfiction about me, using explicit details of my life, my family, my friends, obsessing over me, creating fake accounts to try and talk to me, stalking me online and finding tumblrs i've created when i was like 13 years old, messaging people i know from twitter (my twitter is private) to ask about me, making youtube playlists to try and grab my attention, etc. and i'm so sick of it. he broke up with me very cold and he made it absolutely clear he wants nothing to do with me, and i want nothing to do with him now. it feels like i have absolutely no privacy, and he's been extremely creepy and obsessive and it makes me so uncomfortable. it's definitely not normal to behave like this months after breaking up with someone you very briefly dated and i can't describe how terrible and helpless it feels being stalked, having someone dedicate an hour to writing about you everyday without fail, etc.
i didn't know my ex had aspergers throughout the entire relationship, and ignored all my friends which suggested he did, but he mentioned after we broke up that a specialist at A&E, which he visited after feeling "weird", suggested he has aspergers - there had been no follow ups though, because it was at A&E, and the way my ex mentioned it to me was so casual that I don't know what he thinks of it.
the only reason i'm bringing this up is because of the recent obsession which gets worse DAY BY DAY - and it scares me. i've blocked him on everything and all my social media accounts, etc. are private, but that still doesn't stop him from stalking me. i don't know if he realises what he's doing is inappropriate. i'm not sure what to do because progressively, he is downward spiralling, and it's affecting me - making me feel unsafe, uncomfortable and fearing for my safety (in the past when he's liked girls, he's even tried to find their houses, etc. but at the time i didn't realise how obsessive this was and just passed it off as "oh, he must've just really liked her").
obviously i once cared about him and upon seeing the extent his obsession has reached, i can't help but feel sorry for him - and also extremely frustrated because i'm so fed up of this and want him out of my life. even though he broke up with me, he appears to idolise me in this fanfiction and he appears to think extremely highly of me. so part of me feels like i have a duty to suggest to him he should maybe get tested for aspergers, because this would be beneficial to him and could also help future people understand him better (our relationship basically broke apart because of relationship errors which could've been resolved if we both knew about his ASD). again, i know it's not my place, but by this point there's absolutely no denying that it's more likely he is on the spectrum than not, and it would be beneficial for everyone if it was established. i just don't know what to do - again, the only reason i'm bringing this up is because his obsession is so extremely unhealthy and it is affecting me - if it wasn't affecting me months later, i wouldn't be bringing it up because i know it's none of my business. but again, i feel like i have a duty to inform him, especially because i don't think his family would for multiple reasons.
thanks - and also, i don't want to appear like i'm demonising him or anything. part of this is just me venting my frustration because whilst it was amazing to be in a relationship with him, ever since he broke up with me, i have been put through A LOT that i shouldn't have went through and that i can't be bothered to explain, because i so desperately want to move on with my life - and, no, unfortunately i can't just ignore him if he is literally making fake accounts to try and contact me again.
