Navigating a relationship while grieving

My grandma recently passed away on Sunday and I've been on and off crying, just trying to go through it. But my biggest issue right now is my boyfriend. Over the past year he's been trying to get me to move in with him, but I'm currrently jobless and a student and we could not survive on his income alone, but he doesn't seem to care when I bring that up and just calls it an "excuse". There are other reasons why, but again, he just calls them "excuses."

Despite many conversations, he's still pushing and pushing for me to move in with him. Even while I'm going through this, he still brought it up and kept pushing after I told him I didn't want to have this conversation again.

Outside of this issue, we've been good, but this issue is the one he keeps flipping on; going from understanding to saying all my reasons are "excuses" and to give him a better reason. It's slowly killing this relationship for me everytime we go through it. I've told him this, but he never seems to keep it in mind.

I'm not sure if I should try and keep this relationship or let it go.
