I think it's perfectly understandable that you might have had a crash after things have been going so well. Starting to date after a period apart is REALLY hard, and you've been doing brilliantly at it. But there are still issues unresolved, so of course it's going to take it's toll on you. The great thing is you picked yourself up so quickly!
Re. the tickets- I agree he needs to get them soon. Can you ask him if you can pop something over to him on the way back from your Dad's (and just stop in briefly)? Or alternatively put them in the post- I guess you don't have a post collection on a Sunday there though, so see if he contacts you later in the day?
