We love The CW’s Reign for more than just its lush fashion, pretty headbands, and royal teen angst — it also serves up some serious sparks in the chemistry department.

Mary (Adelaide Kane) is betrothed to Prince Francis (Toby Regbo), who seemingly doesn’t want anything to do with her, but that’s OK because she’s also attracted to the king's bastard son Bash (Torrance Coombs). Love triangle alert! This royal hot-mess-in-training is going to have one tough decision on her hands when the two eventually profess their love for her.

But have no fear, Mary, because Wetpaint Entertainment is here to help you make your decision with seven bits of love advice — as learned the hard way — from these five classic TV love triangles.

1. Dawson, Joey, and Pacey — Dawson’s Creek

This complicated love triangle spanned six seasons and left fans guessing up until the very end. In the end, Pacey got the girl, and lifelong friends Dawson and Joey were better off as childhood soulmates, which was probably the right decision seeing how Pacey and Joey’s chemistry had been undeniable since Season 2.

Lesson learned: Chemistry is everything.

2. Ben, Felicity, and Noel — Felicity

Felicity changed her entire life to follow her high school crush Ben to New York City on a whim, and while Noel was the guy who first wooed her in the Big Apple, Felicity could never shake her feelings for Ben. In the end, poor Noel’s heart was broken (several times), but Felicity and Ben finally had their happy ending.

Lesson learned: Don't be afraid to take chances!  

3. Damon, Elena, and Stefan — The Vampire Diaries

Being caught in the middle of a sexy Salvatore sandwich sounds like a dream, but for Elena Gilbert, it’s more like a nightmare. Stefan is her emotionally rock (and doppelganger soulmate), while Damon is the firecracker vampire she truly loves. In the Season 4 finale, Elena made her choice once and for all, telling Damon she loves him after years of denial — and letting Stefan go find his own happiness. (Unfortunately, he fell right into Silas’s trap, but that’s for another story.)

Lesson learned: Sometimes you have to let the ones you love go.

4. Dean, Rory, and Jess — Gilmore Girls

In the golden age of the WB, the love triangle between Dean, Rory, and Jess was one of the most compelling and complicated relationships on TV. Dean was the golden boy — stable and near-perfect, if not a bit on the bland side — while Jess was the bad boy — smart, rebellious, and a little bit unhinged. So what’s a girl like Rory to do? Luckily, back in those days our TV heroines were smart. Dean couldn’t keep up with her intellect, while Dean often felt threatened by it, so in the end, Rory chose herself.

Lesson learned: Don’t be afraid to choose yourself.

5. Mr. Big, Carrie, and Aidan — Sex and the City

Sure, Carrie and Big’s relationship had more ups and down than a roller coaster, but these two were “absof******lutely” meant to be together from the very first episode. But Big broke her heart when he wouldn’t , and if Carrie hadn’t had the courage to leave the relationship in Season 2, she never would have met Aidan, the man who showed her how she deserved to be loved. In the end, Carrie and Big got back together when he came to his senses and realized she was the one, but he was the one who came crawling back to her. He’s just lucky she said yes.

Lesson learned: Don’t wait around for him to love you.
