How can it be proven that the Holy Qur’an calls for love and tolerance, especially love of enemies, in response to the claim that it contains "repay evil with evil," and what should be done in this relationship?

Missionaries employ various methods, including exploiting women to ensnare young men, as happened with the questioner. The girl did not reveal her true Christian identity until she was certain he had fallen into her trap. Then, she cast upon him the شبهة (misconception/doubt) of "loving enemies." Islam is a religion of justice that calls for justice even with enemies, forgiveness, kindness, and responding to evil with good. It has permitted retaliating evil with its like, yet encourages forgiveness. What this girl says is not suitable for establishing justice; rather, it is submission and humiliation that leads to the loss of rights and the violation of sanctities. The questioner must repent to Allah by immediately cutting off his relationship with the girl and avoiding listening to the misconceptions of the people of disbelief.
