Questioning my aro side (questioning/vent)

For what I think is the first time since I realised I was aromantic, back in June, I feel myself questioning it, not because it doesn't feel it matches me, because it does, but im just wondering if me bring aromantic is a natural occurring thing that's happened, or if it's just a result of my history of relationship pasts or if there could be a connection between it being both

In 2020, my last offical relationship, I went through a really hard breakup, despite that relationship only being under 4 months and semi-long distance (altho the only reason we didn't meet irl was cuz covid) the breakup from that relationship completely and utterly destroyed me, for a long time (like 3 years), and my perception and thoughts surrounding love and relationships, and between 2020 and beginning of 2024 there had only been 1 person I considered taking further then just friends (but got scared and pushed it away etc) and I always said to myself I don't want a relationship again etc and maintained that, even now I feel it.

Then, at the start of this year, I got super close (affectionly and intimatly) quite intensely, with a girl I met in a discord server, but said from the beginning of that, I didnt want a relationship or anything, and said it several times while this was happening, especially as she kept pushing for it. Then it turned out (my 2 best friends, 1 at least was at the time) helped me realise that in fact she was lovebombing and manipulating me (at least emotionally) (I'm autistic and apparently vulnerable etc) so processing that that happened to me was confusing and stuff, but after that I went put my wall back up of never allowing to get close to someone in that way again

I also know there's a common link towards autism/adhd (which I have both) and the aro/ace spectrum which would be more on the "natural occurring" side of what is confusing me

Part of me also feels kinda guilty in a way, because realising I was aromantic and accepting it and stuff, happened really quickly (like maybe within a month), and ofc I researched it deeply etc, but I know many people don't have it happen that easily/quickly so I feel like im a bit guilty for it happening so quickly

I still think and confident I'm aromantic, but I guess just confused/wondering about links/causes when it comes to It
