Your tear then has two fates; firstly it can drain-off down the lacrimal punctum, like the sink plug in your kitchen, subsequently draining through your nose hence why your nose runs when you cry.
Of course in this break-up, you are having a really good old sob, and so your lacrimal drainage system simply cannot deal with the volume of tears.

So in short, your emotional reaction to the break-up triggers your nervous system, which in turn, orders your tear-producing system to activate. What is the point of them though? Is it as simple as an expression in response to a stimulus, as some suggest, or a more complex primal call out - a form of non-verbal communication to elicit help and support from those around you in your time of need? There are some psychologists who believe you feel better after a cry because of this social input, solidifying of relationships with those sharing in the experience, and collaborative helplessness.
