My bf is still drinking he suffers from seizures he takes tablets his stomach is getting big what will be come of him in the future?

Nothing good. Alcohol lowers seizure threshold, so his continued drinking places him at greater risk for more seizures. In addition, his increasing abdominal size may indicate he has developed liver disease and ascites. He should see a doctor as soon as possible, have an evaluation for liver disease and be referred for alcohol counseling.
