From the article…
St. Matthew recorded in the Gospel, “Jesus entered Peter’s house and found Peter’s mother-in-law in bed with a fever. He took her by the hand and the fever left her” (Mt 8:14-15). Note that the passage does not mention St. Peter’s wife, but only his mother-in-law. The Gospels, however, make no mention of St. Peter’s wife, living or nonliving. Therefore, St. Peter’s wife must have died before Jesus called him to be an apostle.
That's a non-sequitur.
That Peter's wife is not mentioned does not rationally support the conclusion that she had died, or otherwise that she was not present; just that she was not relevant to the story being told.
In the culture of that time and place, it was very unusual for a man not to be married. Although none of the other apostle's wives are mentioned, nor Jesus' wife, it is almost certain that most of them were married, and that their wives were alive. If they were single, that would have been very unusual, and much more worthy of mention, than the fact that they were married would have been.
