Loving someone unconditionally means that you don’t have an ulterior motive or unspoken expectation of obligation from the other person. No conditions. Just love. It’s a totally selfless act of caring for another person without thinking about how these actions could benefit you in the future.
You just genuinely want to love, help, and care for someone! And that’s pretty fucking incredible. It’s one of the best gifts that you could give to another person. The best feeling is when this person can reciprocate your no-strings-attached love because it means that you’re well on your way to fostering a healthy and happy relationship!
