I feel like I’m tolerating this strange, harmless, inappropriateness too often now, and It’s making me question if we are right together.
You sound incompatible OP.
I've been with someone who sounds similar to him, nice person but sort of overly earnest in a way that made me cringe and that cringe developed into (this sounds horrible) an almost skin crawling uncomfortableness when he said / did things that were overly earnest.
I also felt like he was projecting onto me the way he thought a doting boyfriend would behave, so none of the things he said were really about me they were almost like him acting out what he thought romantic was.
I also couldn't really be myself because whereas with my now DP we have such a laugh and feel like equals, my ex put me on a pedestal to the extent it would feel almost mean to take the piss out of him affectionately or be sweary and gobby which is my natural state!
It became a visceral ick response and so I broke up with him. He sent me gifts for about 6 months after we split (we'd only been seeing each other a little less than that!!) despite no other contact.
When I said please can you not send things it makes me uncomfortable because I made it clear I wanted a clean break and no contact, he would say "oh but it was too you to not get it for you". Again, outwardly trying to look generous but actually not respecting any boundaries and tbh being creepy.
Anyway, the ick is a permanent ailment I'm afraid. Let him go, then he can find someone who likes the stuff that makes you and me cringe!
