Given theres no way to salvage this, you'd rather have her forget it and start off on a clean slate. In the past when my text game has been awful, Ive burned alot of leads. If you unmatch they can occasionally they pop up again on your feed, and they probably wont remember the conversation but will still think youre hot. As long as you didn't do something outrageously insulting or weird, they wont remember the convo and will prob rematch. Assuming youve improved your text game (be proactive in this regard), theres a much higher chance to get them out at that point. As opposed to doing more bad shit now that paints you into more memorable 'shitty match' territory. Theres a chance you never match again, but this is still best shot for a burned lead imo
