Its how my fiance of six years chose to end our relationship
I had no idea, and had a couple of texts asking me if was ok, from friends. I didn't know they had seen his posts on Facebook (I dont use it) which was where he had chosen to announce that his heart was broken, etc etc.
It was just me he ghosted, it was my family, including my daughter, who was very close to him and loved him, and my two grandsons.
Its one of the most hurtful things that has ever happened to me.
A whole section of my life was pulled out from under me
My contact with his parents, whom I considered my in laws, I still have sporadic contact with his mum, but it has been really too difficult to put behind me.
