Sorry to be harsh but she doesn't want to be with you. This isn't about her trust issues, or any other reason she gives in an effort to let you down gently. She has already told you she doesn't want to be with you and then you turn up out of the blue with flowers and strawberries. That is not romantic that is terrifying! We have too many romantic films that tell us people need to be 'won over', or that people say 'no' but really they mean 'yes but you need to try harder'. That is not real life. Go home and think about whether you are happy to always just be friends with this woman or if ending contact is the best thing. And next time somebody says 'no', believe them.

Women often don't feel safe giving a flat "no". They'll give excuses -- which may turn out to be false as soon as she's dating someone else -- because they don't know which men are unsafe to turn down. If you're continuing to press for a relationship after she has already turned you down, then you have given her more than enough reason to mistrust you. Stop scaring her. Just be her friend or go away.
