Apologies, one and all...

I disappear for months on end and come back with an utterly depressing poem about love and betrayal and no explanation? I'm horrible, aren't I?
This poem was not written about my own circumstances, though, fear not, I am still happily married!! Though I wish he'd do the dishes more often, but that's neither here nor there.
No, see, it's about my sister Taylor (the baby of the family; I have two sisters, fyi). She's a month away from her nineteenth birthday, and she just started school --the same as ME, which is totally YAY-- and she'd been seeing this kid Jack since she was sixteen, and it kind of looked like the whole 'high school sweethearts together forever' type of thing. And then on Saturday, she got a phone call from him (he's at school in California, and is actually a year older than her), and he said he'd fallen for someone else.
Bastard.
Though okay, I get it, people drift apart, and props to him for actually calling her and not texting her or sending her a letter or something. Plus, he had the sense (or coincidental timing, at least), to not break her heart before midterms, because as much as we all love Taylor, I'm pretty sure my mother would have killed her if she'd flunked, even over this.
I'd still like to, I don't know, maybe tear Jack's head off? I mean, two and a half years is a long time, isn't it? And who knows what promises he made that he'll never keep now...
Taylor is dealing, but I can tell she's not the same happy baby sister I once knew.
If anyone has any tips on dealing with heartbreak, please let me know, because I'm at a bit of a loss...
