Years ago, I had a boyfriend who did this! I'd been going out with him for 18 months and although I'd spent the whole of the evening in question with him, he didn't chuck me until we got into bed together. Looking back, I think he was too cowardly to do it face to face, but once the lights were out he found that he could do it. I didn't live with him, but I'd driven there and then had several drinks, so I still stayed the night (in the spare room). No idea why I didn't get a taxi - I was kind of mortified by shock tbh. I also have a friend who was once dumped at the top of a mountain! She and her now ex-boyfriend then hiked back to her car and she still gave him a lift home. We thought it would have been so funny if she'd left him in the wilderness, but on reflection maybe maintaining her dignity was good. What's the shittiest way in which you've been dumped?
