Everyone’s “normal” is different, please don’t feel stupid. It sounds like a combination of you being uncomfortable and him not being patient.
Seems like you two have different ideas of intimacy as well. It could be that him watching you was a way to show he’s focused on you and thinks you’re attractive, but to you it felt impersonal/awkward and isn’t what you need.
Either way, him snapping like that when you were making suggestions was uncalled for. I think taking a break to let things settle is a good idea. You were open with him and he not only ignored that, but twisted it into an attack when it wasn’t one. I wish you the best, OP, but you can’t fix anything with someone who won’t communicate.
