well my piece of advice - don't work there anymore and also don't go to meet again....(if she calls again by email or such)...this is summer break, she will also forget..

if she emails or calls again, then you have to go and meet...but at that time, you can say, you came on this day to see her, but she was not there and later you forgot...

the best advice, don't work there anymore...
