I feel like my boyfriend is getting bored of me😭☹️

My boyfriend (25) and I (25) have been together for almost 4 years but we don't live together yet. I would say we have a nice relationship, it's not toxic and we deeply love each other. Last year he asked me to change my hair color (I'm brunette and he asks me to go blonde). I didn't think anything of it because I know he loves blondes plus I also wanted a bit of a change. I went blonde and the next day he's like I miss the old you... so in 3 months I went back to brown. Last week he is saying he wants me to wear heavier makeup... which I did. And today I get a text from him asking If I can wear the heavy makeup more. I asked him to elaborate what he means (more often or more as in heavier) and he replies back both. Mind you I did a heavy smokey look with eyeliner lashes etc. I texted him back asking if he likes natural or heavy makeup and he tells me overall he likes natural look but once in a while he wants a full black eye look. I feel like he's getting bored of me and that's why he's asking for these changes. I don't know if this is a red flag for something or if I'm just overthinking things. Also I feel weird wearing heavy makeup to restaurants. I don't want to look like I'm about to go to a club. 😩

I think I might be overthinking but I don't know. He is extremely nice to me, gives me a million compliments everyday and he is very affectionate.

I would greatly appreciate some advice on this!
