Then answered Peter and said unto him,"Behold, we have forsaken all
and followed thee; what shall we have therefore?
And Jesus said unto them...
Every one that hath forsaken houses, or brethren, sisters,
or father, or mother,
or wife, or children, or lands,
for my name's sake,
shall receive an hundredfold,
and shall inherit everlasting life."
`
It seems the Apostles had all forsaken ("we have forsaken") the ordinary rights and joys and obligations of marriage and family life, and were willing to sacrifice everything in order to follow Jesus.
It was an eschatological sign: that they were living sacrificially, not for the ordinary satisfactions of this life, but for the everlasting life to come.
Well we will know for certain if the first Pope was either married or a widower when after we go home.
It appears you are confusing what Peter said with what Christ said.
