Getting ghosted advice (help)

I voiced out how i didnt like the way the were acting recently, and they didnt reply or even leave me on SEEN because they “didnt know what to say, was busy” (weird.. cause they be posting) and so i finally hit her w the “was worried about u” and bam ghosted from texts. I cant detach for some reason even though were not close, i feel like im too obsessive... Help how do i let go ITS BEEN A MONTH
