Lol this is like the first time I came across something like this. I don't have an answer to such a question because I've never came across such a situation earlier where my partner asked me to cash out and stuff after hearing something on media or wherever but I think it is that particular individuals choice wether he wants to cash out or keep investing and holding and not the partners choice. I would say is like the partner should respect the others choice and not force him/her to do something they don't want.
