Is my garage about to collapse?

Have been renting here for 5 years. When we moved in the cracks were about 50% smaller but would shift occasionally. But the side brickwork is definitely coming further out which worries me the most. My landlord is very stingy and we're concerned about rental increase if he can justify it by spending on this repair. Is there a cheap(ish) simple way to hold this together well enough for another few years? It is just this back corner and a bit of the middle of that side that has significantly shifted. Other 3 corners are solid, brick work mostly intact and the beams haven't bowed
