When have you sat down to actually talk to her and asked her for it instead of being angry and hate/angry f*cking her?
I know this is just the way it's written but i get so annoyed when they make the ml be a jerk who forces himself upon the mc because he's angry, jealous, whatever and make these accusations of the mc. Then when they find out they're all 'oh there's some info missing. Why didn't/won't they tell me now so i can know?' after stopping any attempts to explain.
They don't take accountability for their part and put it all on the mc.
MC should speak up though in rare cases i understand some are so abused, beaten, and damaged that they can't. But some are always "oh there's no way he loves me. I'm just his fwb, but that's ok since i love him."
