When I was with my ex, I was planning to move in with him while attending university. I wanted a plan in place in case we split up, as being homeless could have cost me my degree.
However, he refused to talk about it, yelling at me, "You're talking about if we split up! That means you want to split up!" I couldn't get any sense out of him.
Naturally of course, we did split up - before I even started at university (he cheated on me).
