Brainstorming: A Guide to Inter-species Dating

I'm doing some brainstorming to make sure I have enough to write for the August Session of Camp NaNoWriMo and I could use some help.

I'm putting together a short story collection using advice given to couples trying to date outside their species and I need some more bits of advice to use as writing prompts. Here's what I have so far:

-Nobody likes a Stalker
-Once's she's dead, she's no longer your girlfriend
-An eternity of pining may seem romantic but the reality is pretty boring
-Love triangles aren't as fun if you are the only mortal
-Not all walking corpses are created equal
-Sometimes the chase is the best part
-Compatible lifestyles are very important
-Being eaten out is fun. Getting eaten? Not so much
-Sometimes magic isn't enough
-Bringing your lover back as a zombie is going to be unsatisfying for everyone
-If you can't touch, then maybe you aren't meant to be together.

So far this collection is a mix of Faeries, Elves, Humans, Werewolves, Vampires, Zombies and Ghosts. Also, lots of poking fun at common paranormal romance tropes.

So, what advice do you have for these poor couples?
