When he met me when I was ridiculously hungover after drunk messaging him the day before, he teased me like nothing else but also made sure I'd had a lot of water and coffee and painkillers before I headed off back home.
When he charmed my mother because he 'takes care of me' not sure how she figured that out we spent our time arguing over board games and wrestling for a torch 
but apparently he gives off that vibe and she likes the way he looks at me.
When he visibly liked seeing how close my family are and seeing the 'huggy/tactile' me who lets her aunt grab her face to kiss her cheek and will hug and kiss their aunt and mother just because I was walking past and wanted too. He liked how close and loving and free with affection we are, tbh our other friends who were with us did too but he was bizarrely pleased about it. When the option was for him to meet my marvel mad 8yr old nephew and my 7yr old niece or go to the beach he insisted on meeting my nephew instead and went out of his way to wear a marvel themed shirt because my nephew would like it. He was also very pleased by how happy my niece and nephew were to see me. They reacted by jumping and tackling me to be held and lifted and cuddled while shrieking my name and I was happy to oblige. I adore my nieces and nephews. He was also great with my nephew and thrilled when my nephew announced that he was one of his favourite people (other than me my nephew hasn't met an adult that likes marvel who is willing to sit and debate the ins and outs of the universe with him) that and my nephew checked that he knows I'm autistic and asked if he'd look after me he promised he would. (We were not dating but going on a group's holiday with other friends)
When we were on holiday and I panicked basically every night in the crowd and he alternated by using himself as a human shield and holding my hand so I'd stay calm and leading me through it without it being a bother or inconvenience or me even having to tell him I was struggling, he just knew.
When he hinted at wanting to be my plus one to a family wedding (something I didn't realise till after the wedding because yay autism 
), and talked about his wedding and my wedding not necessarily the idea of us getting married but what I'd want versus what he'd want and how they'd fit together.
And when he said that he wants my family to like him, in response to my saying that I'm not sure how my family would take to him. He was oddly pleased with how highly my mother thinks of him and that my family want to meet him and take him out for a few drinks. Especially my grandad.
Have to add we're not dating but ideally I'd like to change that if I can. If not I've a great friend and whoever he ends up with is incredibly lucky and I will measure my standards of a man and how a man should behave against him.
He knows I'm autistic and it doesn't phase him at all, his dad and older sibling are so there is no condescending or assuming of my abilities or needs, just acceptance and a spark which is rather fun.
