Sweetie, trust him until he gives you reason not to.
You went on one "really fun date"... you're not quite in a relationship with him, you're testing the waters to see if you two could develop into something...
He was the one that asked you for a second date. Normally, when a guy isn't interested, he doesn't ask. He skirts the issue, makes excuses, etc. etc., but doesn't ask. Trust him that something really did happen with his relative.
Just wait. Wait for him to get back.
The only way you can trust him is to Just Do It. Trust him until he gives you reason not to. That's a good way to approach any relationship.
Take this weekend as a You weekend. Go get a massage, get your nails done, rent chick movies, and eat lots of chocolate. Make it about you. Don't worry about him
