If you really want to go on a date, be upfront in whatever app or service you are using. If you have free time, just enjoy yourself because it sounds like you will be busy wherever you are going. Don’t expect to have a long term style relationship in this short time, long distance is difficult and I’d advise against it. But do whatever you think is best, everyone is different including their SO. Best of luck
I read that Sony is doing it for security reasons for safety/grieving and that the game did originally require a PSN login at launch, but stopped it at launch. But I am guessing this is just them saying hey we have this many people using PSN accounts. No other reason to have Steam prompt for login for anything besides the Steam account
