My boyfriend is probably not the one but he thinks I am

Hi, I (F16) am in a relationship with my boyfriend (M16) for 4 months and i deep down know he is not “the one”. I love him a whole lot and I love and enjoy spending time with him but i know he is not the one with whom I want to spend the rest of my life with. There is no reason why i feel this way, we match pretty well but I just kinda know it.

The problem however is he is really head over heals for me and he is sure that I am the one for him. He says that I am perfect for him and that one day we will move in together, get a dog, going to concerts together, etc. and then he always looks at me with those eyes full of love. I think it is very cute but tbh I feel a little bit pressured by all his words, i don’t think that i am as perfect as he claims. It feels like he doesn’t see my imperfections and only sees the good in me. I once told him I had flaws too and then he laughed and said: ‘If you have flaws then you are very good at hiding them because i don’t see any’

I feel so bad that I don’t think that he is the one but i don’t want to break up because I got really attached to him and still want to put in effort in our relationship and enjoy every moment with him + he would be so heartbroken if I left him or even told him that i don’t see us being together forever. Life is long and we are only 16, it is my first serious relationship with someone I really care for and idk what to do. I am such an egoïst for staying with him altough I don’t love him as much as he loves me. It feels like I am leading him on. I don’t want to hurt him.

Wtf should I do? T T
