This is so sad in a way that feels very true.

'I prefer to hoard them in my heart

but one by one they crack their way out'

That line makes me want to cry, but I love it.

It is exactly how things go with me and my relationships. You really have a lot of knowledge, don't you? Not only of the general norms, but also of abnormal ones... That's what makes your poems so intriguing to read.
