The problem is, you don’t know where he’s been! For all you know he’s one of those people who think the whole covid rules don’t apply to them and has been out with his mates, he could even be what they call a super spreader who shows no symptoms, or he might be just a very nice guy. I’m afraid all the usual rules about dating have been thrown out of the window, and you can’t get to know someone on Skype and a couple of dates, so you don’t REALLY know this person at all. And to say he might not be able to resist giving you a hug is a bit of a red flag. Make it plain you’re not going to hug and stay your distance. If he really likes you, he will respect your boundaries and be willing to wait.
