Unconditional love can never exist on this earth, excluding God's unconditional love

I hope to rebuttal his arguments. First, I would just like to say that both my opponent and I agree that God's love is unconditional, so it should not be held against either one of us. I only added it to the resolution to set a restriction. I would also like to say that this whole week, I have had to take care of a sick relative. I just have a couple minutes, but I have truly had no time this week to debate. I apologize greatly, but I will try to come up with a decent argument before the round is up. The thing you said about John killing Mary's family, you totally said something different second round than first round. Originally, you said that she would probably leave him, which means her love for him would in some way change and be conditional. Now, you say that he will be sent to jail and she will still love him for she could have hated her family and not cared. How about if he killed everyone she loved, the world, and herself? Her love would have the condition of possibly changing, and that's all I need. For you whole list of things that are "unconditional" loves of yours, you have no way to prove your love for them is unconditional. You simply stated your love for them was unconditional, you gave no evidence or reason why they are unconditional, just saying they are is not enough. I could simply rebuttal by saying:My love for faith is conditional, my love for honesty is conditional, etc. You gave no reasoning or proof. Love is very abstract, and you did not explain why they are unconditional, for the things you listed were very abstract and conditional within themselves. The thing about the mother and the newborn baby, how sweet! But your reasoning behind it is faulty. You say mothers love their babies unconditionally, but that is an assumption. There are moms that do not love their babies, they find problems with them. But I will rebuttal the common situation that you speak of. For it to be unconditional love, the mother would need to love the baby under all possible conditions that occur with the baby. If the baby grew up and killed her loved ones, the earth, and herself, that is a condition where her love would change. All I need to prove is that there would be one condition where the love would change. About what we can and cannot love, you have to prove that in fact unconditional love truly does exist. Saying that there is a possibility it would not chane is not good enough within itself. How can you say love is unconditional? Love is very abstract, and some people say they love others when truly they do not. There are different emotions and variables that go along with love, so how can it be unconditional? Love is a condition within itself, and it tends to change as people go through stages of life, involving things like maturation and hormones. You have not proven that there can be a constant unconditional love. The phases and stages of love are always changing as natural occurrences changes and as people grow older. Unconditional love cannot exist on this earth. I believe I have successfully proven the resolution. I thank the readers for their time and hope you can forgive me for my late round entry, my relative has been sick this entire week. Thank you
