How can I make sure that a certain romance in my stories will not end up like "Twilight"?

The main thing is to make sure your character has depth and meaning outside of her romance. What drives her? Why did she fall in love with this/these people? Also, you could read The Hunger Games trilogy and focus on figuring out the love triangle there. Although that's still to relationship dependent for my choice. I hope this helps!

You're writing it - you decide whether it's too close to Twilight for your tastes or not, and rewrite it if you think it is.

I'm afraid I laughed out loud at the concept of it getting too much attention, or "heavy trollage" being inevitable. Chances are that a couple of hundred people will read it total, and maybe one or two of them will flame it and move on.

Unless you have a sparkly vampire close to a century older than the object of his affection, who mistakes obsession and control for love, you're in no danger of ending up like Twilight.

Don't have a wooden protagonist who finds being stalked romantic, or so stuck up that she's rude to people who are trying to make her feel welcome before dumping them all at the drop of a hat for a guy.

As long as you give the characters a reason to be in love with each other(besides physical appearances), you should be fine. Making them not whiny would help too.

Like Twilight? You mean insanely popular?

twighlight was bad because it had no depth and the story was wiriten extreamly vaugely. if you want your story to not be like twiglight you should use words and literary style to write the feeligns of the cahrictors

I think u should just make sure there are also other things happening in the story not just the relationship... In twilight all it talks about is a relationship and how she needs him bla bla bla...
