Camping overnight sounds like booty call. Being in the nature or outdoors or outside is a great date. Walk in the park, picnic, nature center, coffee date with a walk in town etc Overnight camping if he can’t find time for dating is weird. Overnight trips are appropriate when you are actively dating for awhile

If he is too consumed with grief to give you a phone call, why isn’t he too consumed with it for camping trips?

Dude is bad news. Not saying he’s dangerous but the way he goes about things isn’t promising. This isn’t going to be anything of substance
