Love means different things to different people - and I'm not talking about the 5 languages of love.
Love is the person whom you're the most comfortable with, even if you feel miserable half of the time. The fact that you're so comfortable being the worst version of yourself means that you love them in your own weird, unhealthy attached kind of way.
Personally, I don't define that as love and neither do most relationship/marriage/psychologist counselors/pastors. What you have is an unhealthy attachment and trauma bond, but hey, whatever works for you.
