Translation - Dutch-English - Ik denk constant aan je!

Steadly? Is that a word? Steadily is but doesn't work here. Why not 'constantly'?

Hi Lein. Yes, I wanted to write steadily, but you are right, constantly is the right word, but can see that Lilian have used a synonym "incessantly, which is quite good, I think.
Thanks for your help.

I think about you constantly
