Brian Blume persuaded Gygax to allow Brian's brother Kevin to purchase Melvin Blume's shares. This gave the Blume brothers a controlling interest, and by 1981, Gygax and the Blumes were increasingly at loggerheads over the company's management. Gygax's frustrations at work and increased prosperity from his generous royalties brought a number of changes to his personal life. He and Mary Jo had been active members of the local Jehovah's Witnesses, but others in the congregation already felt uneasy about Gygax's smoking and drinking; his connection to the "satanic" game D&D caused enough friction that the Gygaxes finally disassociated themselves from Jehovah's Witnesses. Continuing to resent the amount of time her husband spent "playing games", Mary Jo had begun to drink excessively, and the couple argued frequently. Gygax, who had started smoking marijuana when he lost his insurance job in 1970, started to use cocaine, and had a number of extramarital affairs. In 1983, the two had an acrimonious divorce.
