Did I f*ck my ex up bad?

I texted him I was done (we dated for like 2.5 months) and then ghosted him it’s almost been two years now and I haven’t spoken to him since that day I told him I was done and never told him why I was done. I’m happily engaged now with a wonderful partner but I constantly wonder how bad i probably ducked him up.. what do you guys think?
