My sister, if you haven't already discovered this for yourself, most Christians are more concerned that they have free will, i.e. the ability to thwart God's will and bring his counsel to nothing, than they are that God's will be done, even if they pray:
"Our Father, who art in heaven,
hallowed be thy name.
Thy kingdom come,
thy will be done...."
It is proof that Arminianism cannot be accomplished in prayer to God simply for the fact that we are taught to pray that His will be done, not laud that man's own will be done.
But, all of that aside, if this verse in 2 Peter is really to mean that God is not willing that any perish, meaning the whole human race without any exception, then how are we explain the fact that the Lord was unwilling to work miracles in the presence of some whom He knew would repent in the face of those miracles? (Matthe 11:21)
How are we to understand that the Lord spoke in parables so that people would not discern and understand so that they would NEVER turn and have their sins forgiven? (Mark 4:11-12)
It sure does seem as if 2 Peter really does mean that the Father is unwilling that any perish that the Son was actively working against the Father. Are we suppose that the Father and Son are at war with each other? Is this what the Trinity really means to Arminians?
