When a Leo Male Ghosts

We talked about getting back together- I may have been a little too open and honest- I told him I didn’t know if it was a good idea. We talked a few times after, but there was something off and he went ghost. I tried calling him once four days after, he didn’t answer it’s been almost two weeks. He posted a RIP piece of artwork online.

I really like this guy, but damn he makes me feel crazy.

Is there anything I can do?
