I hate to be the bearer of bad news, but it seems very likely that you are not highly appreciated by your new boss. He is probably hoping you quit; he's not doing anything to encourage you to stay. I doubt he will offer much in the way of a raise to keep you on.
In a situation like this, the fact that you are infrequently on site has probably contributed to your ending up on the short side of the stick wrt office politics. You have likely missed important social cues related to the new boss' style and expectations. You have not been physically present to make sure you get credit for your work, and to counteract any negative karma that might have been thrown your way.
No it's not exactly fair, but employment is generally 'at will', there is no guarantee of fairness or bulwark against capricious or petty treatment.
