The tragedy of the story in Genesis chapter 3 is that it always seems to be blamed on God. Adam and his wife had been given very clear instructions on what they should do and more particularly what they shouldn't do. They made a choice, albeit under the deceitful lure of Satan, and they chose to disobey God.
Before moving on, let me make one very important point. They were able to make that choice because God, the Father, had given them the priceless gift of free will. In giving that gift God took a risk because it is only the gift of free will which enables us to love. Without it we could not love because love is always a choice, it is in our power to love or not to love.
And so at the end of Genesis 3, Father God has to make the painful decision to drive Adam and Eve out of the garden. Too often we view this as an act of judgement, the punishment for sin and a wrong decision. Can you view this not as judgement but rather as a tremendous act of mercy? It was an act, however painful, which prevented them remaining in the garden and being able to eat from the tree of life. The result of which would have been living forever in a fallen, broken state. God knew that was too much for mankind to bear. Death entered the human race to save us from ourselves, or at least to limit the extent of the damage we had caused.
In that moment God did not change, nor did he abandon his plan; the plan he'd had from before the creation of the world. The plan for relationship and family has not been shelved, it continues and is the same plan (the only plan) that the Father has for you and me.
For I the Lord do not change; therefore you, O children of Jacob, are not consumed. From the days of your fathers you have turned aside from my statutes and have not kept them. Return to me, and I will return to you, says the Lord of hosts. (Malachi 3:6-7 ESV)
It was mankind that chose to walk away from the Father's plan. The Father did not change. He is the same yesterday, today and forever. His plan and desire is the same today as it was in Genesis chapter 1.
