“But I still love him”

I suspect your learning that love does not mean that relationship will thrive or last. That you can love someone even as you end a relationship. Perhaps even that Love requires that a relationship end.

Responsibility, accountability, discipline, meaning, growth… are all attributes of the experience of love.  Love requires that we hold those we are in relationship with accountable and sometimes that means the relationship must end. Ending not because you do not love but because you do love. Love continues even if a relationship does not.
