Between Ciara and Rocko, Future has a lot of big money lawsuits to deal with.

No he has one fewer.

TMZ reports that Future is no longer counter-suing his ex wife -- who is still suing him for $15 million for defamation.

Future decided to drop the suit because he prevailed over Ciara in family court last month and won joint custody of Baby Future.

He is concerned that if he continues to go after her in court she will retaliate by trying to get the custody decision reversed.

He'll also have more time to concentrate on the $10 million breach of contact suit Rocko just hit him with.
