Welcome to the forum, Stupiddave!
If your wife has always cheated on you through the years, that means you are not a wannabe cuck. It means you are a real cuckold.
Please recall the definition: cuckold — a man with an unfaithful wife (meaning, of course, a wife who fucks one or more other men).
Whether a cuckold knows or does not know his wife is fucking other men, or knows and does not approve of that, or knows and approves of his wife fucking other men, or even assists his wife by helping her find other men to fuck, are all unrelated to the basic definition of a cuckold.
