He didn’t say i love you back…

Hey y’all

This is a long distance relationship, we video call, talk on the phone regularly and text.

We been dating for like 2 months. I felt like I know a substantial amount of who he is, but i guess you never really know..

We send love letters via mail to each other

And yes i am 21

But i told him i loved him yesterday but he didn’t say it back, should i be worried?
