A list of solutions that could literally have saved the lives of several opera characters:
End up as a polyamorous relationship
Be respectful of other people’s boundaries
Wait for at least a short while before engaging in drastic actions
Use your brain to think rather than your heart
Use strictly non-violent solutions to get what you want
Don’t do certain things solely because you’re crazy in love with someone, you will regret it
Settle for better person in the cast as a romantic partner. Maybe it will work out? Maybe it won’t? At least there will be less blood.
GET AS FAR AWAY FROM YOUR TOXIC LOVE INTEREST AS POSSIBLE
No, seriously, using your fucking braincells will save lives, including your own, especially your own
[there’s probably more I could include, but you get the idea]
