Hey! I haven't read your whole sitch, but you need to leave her alone. Go and do your own thing. Go NC/Dark as much as possible. Stop pursuit and pressure. I know you're hurting, but all of this behavior is sending beta male signals to her, which makes her lose more respect for you. Don't suddenly turn into a macho man, but start handling your own business and let her go on her path. You need to find yours.
