I told my crush I liked him and he went ghost?

I just told my crush in a text, hey I just like you. and here I think that's a compliment to tell someone you like them? after I sent that text I got left on delivered and ghosted. I don't get it. we have a fun time and kissed too when we got together? he gives me the idea he likes me when we are together. he added me back on Facebook last night. but won't even open my Dms now. What happened?
