@helpfulAvocado5122 could I say personally?
It's very personal. In my own experience, true love is when you feel for someone something that is beyond anything in the world. A wish of being around the person, to protect, to stay in the good and bad times, to be happy for their happiness, to be at any moment, no matter what happens and what is happening with you.
It's to put your own needs at second and to be able to learn and change for the best of this person.
Of course, it depends on the situation and some things have limits.
But love is that. Donating a part of yourself in the benefit of the other and being complete with that.
