There is a man who is 49 who I get on with at university. He’s very sociable and charming. Him and other girl in our course arranged to meet a few weeks back but we didn’t go because the other girl couldn’t. So today he asked if we would go out again without the other girl present there, saying that even if the other girl can’t come we should go out together alone. Unfortunately, at the time I’m free on that day she isn’t, and I’m not keen on hanging out with a 49 year old man just us and I think he knows this. Do you think this is reasonable of me?
