MC should go for it. What’s her flaw? She likes him too much?
The issue with crazies is, when they get obsessive they can start:
poisoning your food and drink with sleep med or aphrodisiac, threaten (or actually) cut you or themselves, and then it ALWAYS escalated into straight up actual harm to you or them as threats to make sure you feed their needy attention every few minutes, of every single day.
Imagine waking up to 90 texts ranging from death threats, pleading, self-harm threats… daily.
It isn’t fun. Don’t do it.
