Solved!!! First off you get exiled because Trevor kidnaps the mexican guy's (the guy whos house you destroy in vinewood hills) wife. This is not mission so you don't know about it until a mission where you see the guy's wife in Trevor's trailer. Now in order to regain access to the city you must complete the mission Monkey Business and the mission where you steal the gold idol from the train. This will cause Trevor to hand back the mexican guy's wife and now both Trevor and Mike are allowed back in the city unharmed.
The games ****, i can't do anything my last mission was minor turbulence and now I'm exhiled from the city , I'm not stupid , there's nothin i need to do , the games clitched plain and simple
Edit: removed profanity

Sorry. I was just really confused. And frantic. And I was just ready to hear another answer to ease my mind before I shut this down.
