should i fall back

the guy I'm currently seeing is amazing, just one thing him and his phone, he takes it everywhere doesn't want me to know his password is very secretive but tells Me not to worry, we are supposed to get a place together soon and I don't want to ruin us or that, but I've said it to him jokingly, he kinda gets annoyed and tells me to stop all that.

I also told him I loved him, he didn't say it back.

I feel like an idiot.
