In my opinion unconditional love is a destructive thing, especially when it isn't mutual. And I say this for both the giver and the receiver, because love itself is a destructive thing unless it kept between the boundaries. It is a glorified fairytale, an obsession that someone will love you no matter what harm it does to them, and vice versa. It blinds you, and an obsessed person will go any lengths to satisfy their self-satisfaction. "They will never love you like I do, they can't. Because my love is unconditional and I will keep destroying myself to give everything of me to you. And as I heal I will offer it again and again like a person who finds amusement in picking their skin again and again." It is very unhealthy, yet a lot of people see it as the epitome of "the perfect relationship," where two people would quite literally die for each other because they are their partners and they would lost all meaning in life if they are incomplete.
I have experienced that kind of unconditional love but maybe maybe I'm now more of a person who cares for a platonic love than the romantic one, but I think it's better. Of course to love someone means to accept their flaws, to be fully understanding of what they might be going through, to not let the distance intervene you and them because how precious they are to you. But love to me have conditions. Because there will be a time you are done destroying yourself for someone who wouldn't move a finger for you and labelling it as unconditional love, saying to yourself that it's such a tragic but beautiful thing to do, because your heart is no more at that point. I have realized that love can have small conditions, and that's okay because if I were to truly love someone I should be able to fulfill those conditions.
And I'm not talking about not accepting your loved ones for who they are but helping them grow and improve as a person as well. Some people can fell in love with someone's potential and call it "unconditional love," because they will keep doing anything to build or preserve that image in their head instead of seeing them for who they are: someone who knows that you would do anything for them, living or dying, and use that as a leverage against you. Love with conditions can sometimes be beneficial, it helps you see if they are harming you or if you are harming them, if the conditions are reasonable (here, let me stress on the word "reasonable") and it helps understand them better too. Why they request what they request for.
All of these sound hella romantic, but it will slowly eat you up. Once you get used to it, once it is the norm, your definition of true love, it will push you away from everything you once loved, your family, friends, hobbies, yourself. It's not a sudden, obvious process, it's incredibly slow and it will creep in on you and stay attached without you knowing. Only when you put massive efforts to escape and heal you can see how much damage it did to you and your perception of love itself.
This is not to say true love doesn't exist, but that unconditional love isn't as good as it is portrayed to be. Of course you can disagree with me as I share just my own opinion.
