What’s normal affection?

I (22F) have been on a few dates with 24M.

I don’t know how to read people and body language, I’m not sure what’s considered socially acceptable.

(some background info: I’ve been in a lot of very bad relationships and situationships, where I’ve been mistreated)

It’s been going really well and he’s very very nice, we’ve kissed but not gone further than kissing. He’s very affectionate, he always initiates physical contact but never inappropriately e.g. he always initiates holding hands and he’ll caress my palm with his thumb, or if we’re kissing he never touches me inappropriately, it’s all very respectful. He also initiates kisses, he holds the door open for me, pays for dates but has made no sexual comments or even hinted at hooking up, he also refers to our meet-ups as dates even when I don’t. He’s twice suggested he could cook for me at his place, which I guess could be a hint.

He compliments me a lot “you have really pretty eyes” or “you look great” etc. He compliments me in general, especially if he’s about to kiss me. We¨’ve been on 3 dates so far, and it’s gone really well I feel comfortable around him, but my brain is convinced it’s all fake, and not real. He also said he likes me on our last date, I don’t know if that’s normal or not. I’m an overthinker and also Neurodivergent, I have no idea what’s considered normal affection and what isn’t, I’m used to ambivalent behaviour from people I’m dating or talking to, but he’s not displayed any ambivalent behaviour at all. I don’t know if the physical contact level is normal or too much, if the compliments are excessive and if it’s weird to say you like someone after 3 dates.

I am out of my element and not used to this, and idk what to think because idk what’s normal.
