Calypso isn't exactly as much of a victim and innocent as everyone else perceives she is because she was trapped on that island by Zeus. No, no Calypso is very aware when, where, and how to act to easily bend others to her will. As she is desperate for this toxic relationship between the two of you she calls 'love'.
But it's not, this is pure evil. And she's doing all this because what the hell are you supposed to do about it? You're not an immortal water nymph like she is no, your only mortal. A very weak mortal she doesn't waste any time preying on once she realizes how vulnerable you really are after all that's happened to you.
She doesn't care about that either, just you and you alone. Remember, this isn't a good thing at all so you should really be trying to escape. It's hard when she's watching your every move on this damned island though, huh?
You've been suffering by her hands for years now- seven years to be exact and she still has the audacity to act surprised when you finally snap. When you finally say enough is enough and want to end it all. Gods, you're so tired, you just want to close your eyes after all of this...
But she won't even do that, fucking clingy psycho. "Stay in my open arms!" Calypso exclaims, clutching the fabric of her flowy white dress tight, frowning. She just wants you to stay with her forever, though she won't tell you she's made you immortal yet with how she's been mixing ambrosia in all your food this whole time.
She really, really can't help that you've gotten her wrapped around your finger since you first washed up on her island. There's no way she's letting you go now, never would she dream of such a horrid thing. Even though she knows Athena, the Goddess of Wisdom herself was your mentor and now flies over the island everyday she isn't against fighting tooth and nail to keep you either.
Please, just stay in her open arms forever and ever. She promises she'll take very good care of you and keep you far away from harm. Your love together is pure you light up her life.
