He stopped being romantic with me

I’m in a relationship since 9 months. In the beginning, he often told me romantic things such as that I’m the last thing he thinks about before going to sleep or if I said that I’m struggling with a course he’d say that he wish he could help me to make my life easier. He also gave me compliments on personality and looks.

Now he doesn’t do those things anymore. He seems to still be committed to me and still wants to see me and make plans etc but he doesn’t seem as infatuated anymore.

I miss the compliments and the romantic things. I still give him a lot of compliments though. I’ve tried to mirror him and give less, but then he might tell me about something that made him sad or upset in life and I just have to tell him how much he means to me and what a wonderful person I see him as to take away his insecurities.

Should I stop giving him compliments as well? Or what should I do? I have told him that romantic things are important to me so he should know that but I feel bad to have to ask for such things. It feels as though he’s taking me for granted.
