What do I do!!!! HELP

So I’m gonna make this long story into a short one.

I told my boyfriend that I loved him. He said he wasn’t ready and now is freaking out bc he thinks our relationship won’t be normal now.

He says it’s not fair that I have those feelings and he doesn’t yet. I’m okay with waiting for him. I know that people don’t fall in love all at the exact same moments. He is now saying he just needs time to think and I don’t know what to do, bc I love him so much, and I can’t lose him!!! 😫😫
