I dont think the FL is weak at all. Yes, she attempted suicide, but what she went through was fucked up. Not only was her lover planning to leave her and marry another woman, but he had the audacity to act like she was the one who was leaving him, and everyone she trusted knew and kept her in the dark. When she tried to call it out, they treated her like she was in the wrong. In addition to being falsely accused, starved, imprisoned, and drugged, of course she wouldn't be the strongest person ever. Also, the best thing about her is that she isn't stupid enough to stay in a situation where she has been wrong or hold on to someone who has hurt her.
