Yep, just forget him. Live your life, and if he calls later and tells you he was going through something, I'd be more cautious about moving forward, slower.
He could just be a player. Often the most charasmatic and charming people who you think you "connect" with, instead have some kind of narcissistic personality disorder or who knows what. But don't believe everything you see in a guy till you see his bad side - everybody has one- communication skills(can he work things out with you or does he just get defensive?RED flag)
I know someone where the guys often lost interest fast becasue she was the one calling and texting the guy first all the time. They had no chase, that classic need for hunting (as corny as it sounds) so it was a turn off. She looked desperate just from that. I do not know if that is the case for you but hopefully I've helped a little.
Oh also, guys easily get turned off by girls who have no other life than him. They often think its a little pathetic if there is no ambition, no involvement in outside life, if she has no other world than him. THIS is very common for girls, for a lot of reasons which I won't take the time to go into. BUT if you'd like to change your life a little or just need a distraction from this guy who left you hanging, here's some GOOD reading:
Honestly, Every guy girl young or old should read these.
First - the psychological pillar upon which all other things are based. ready? "How to Raise Your Self Esteem" by Nathanial Branden. its important.
Second - Loving Him Without Losing You (ok this one, not so much for the gents)
Third - Is it Love or Is It Addiction (forgot who its by) third edition
Last - The How of Happiness - by Sonja Lyubomirsky - she was given 1 million dollar grant to research happiness, and its findings are fascinating. It tailors a plan to you by the quizes you take and ya there's a lot more to it but its quite amazing.
Good Luck Darlin.
