Did God Have A Wife, As I Never Hear Anyone Speak Of Her?

No, not in the sense you are talking about, God is Spirit...
Bu, Jesus is the Messiah//Christ, all through old testament The triune God's plan was for him to take on the likeness of man,to redeem man back to himself, Jesus refers to his followers as the bride of Christ. His followers are the Church. When I say church, not baptist, methodist, catholic,
ect,but all people everywhere who have placed thier faith in Christ, and Christ alone.God calls the church his bride, So yes in sense all born again followers of Jesus are the bride of Christ.
In the future we are going to have ( Marriage Supper of the Lamb) I do not mean we are going to eat lamb, but become one with Christ all thru eternity

No god doesn't have a wife nor an equal (that's from the muslim perspective)

No, for the very good reason that God is female - and black!

No. Since God is spirit. He would have no physical desire for a mate. And, as God is complete in Himself, He would have no emotional, mental, spiritual, etc. Need for a counter part or partner, in any other sense.
