What should I do?

I been dating this guy over two months now... he was my friend and then one day I kiss him and he got super excited that we started dating but sometimes I feel like I am not as happy as I used to be be on my past relationships.. he’s good guy, does everything to make me happy and I really appreciate that but we only see each other like two times a week.. we have meet our families but I still having that feeling that we are missing something, what’s wrong with this? I talk to him and he’s all about “you are perfect, i love this relationship” but every time he said that I am the love of his life I feel bad that I can’t say the same and if I do I feel like I am lying to him.. what do I do?
