Boyfriend Not Showing Affection

Overall he’s a sweet guy, and in person he shows his affection in different ways. But since we’ve gone long distance (quarantine), he rarely compliments me, expresses his love for me, or shows me appreciation. I feel like I do my best to remind him that I miss him and can’t wait to see him again, but he rarely says “I miss you” first and doesn’t seem bothered if our plans to see each other get postponed or canceled.

He facetimes me almost every day, which I’m thankful for, but on days we don’t talk there’s literally nothing. No gm/gn texts or anything to show he was thinking of me. A lot of times I’ll text first, and it usually goes something like this:

I hope I’m not overreacting/overthinking it. I just like to be reassured relatively often that he cares about me and enjoys having me in his life. I’ve brought it up with him before, but he just gets annoyed and says he wouldn’t be calling me if he didn’t like spending time with me. I just wish he’d reciprocate the level of affection I’m giving him, even if it’s just by calling me a cute pet name or something (he does have “pet names” for me, but they’re not romantic at all and he calls his male friends by the same ones...lol). Would y’all be bothered by this too, or should I just accept that this is how he is?
