Keep your glue in the fridge.
I have a glue fridge instead of a beer fridge. Everything adhesive goes in there, lasts way longer. Even opened tubes of roof and gutter silicone will last for a year or so minimum. Two reasons, one is the cold slows down chemical reactions and the evaporation of solvents (as in the case of patch glues), and the other is that the cold reduces the humidity and a lot of glues are moisture activated,
