Hi
I agree with ptang, to have certain expectations from an online partner is dangerous for the heart. Online Relationship Responsibilities are different, I guess this means it's easier to walk away or get uninterested when another interest appears.
Having said that, it's also not an excuse for what he has done to you. He should be more sensitive towards your feelings especially now that you have moved to a new place and your concerns at your workplace.
What's next? Move on as ptang mentioned.
Many online friends out there to be made, and part of the fun is filtering the weirdos from the genuine ones.
Btw it's common to work under bad bosses, give it some time and I am sure something will pop up. Remember, You just moved to a new place! New opportunities might just be around the corner!

Good Luck!
