I told my crush how I felt but he didn't respond?

I texted my crush to see if he was interested in getting to know each other more. Apparently he forgot to save my contact from a previous interaction so the only response I got was about who I was, but after I told him he just liked the message and was silent.

But that's not where the story ends.

A few days before I texted him about my feelings, I followed him on his insta and he didn't follow me back. But on the day I told him how I felt, despite not giving me a yes, no, or maybe, he then followed me back of insta (note that this was immediately after I told him it was me)

So could this mean he has an interest?
