Your intuition suggests something isn't right but you're not sure what it is. It is not until the aftermath that you can see clearly & realize that true life can be more terrifying than a horror movie, that monsters are real & EVIL preys on the innocent.
Survivors need to understand this. How many times I told myself, "I could have lived my whole live without being loved like THIS." Because it wasn't love, just an illusion that fulfilled his needs, until it didn't any more.
And maybe a happy ending doesn't include a guy, maybe it's you on your own, picking up the pieces and starting over, freeing yourself up for something better in the future. Maybe the happy ending is just moving on.
