I just had this happen to me. We were talking about moving in together and starting a family. Then we had a discussion about me feeling him be distant recently and that he didn’t seem excited to move in together and he shut down. We were supposed to take a trip that very weekend and instead he completely ghosted me. It’s been 3 weeks now and we work together and he can’t even just get the nerve to explain what happened. He had just completely taken me out of his life and I have to see his face every day.
