I don’t think it’s as cut and dry. Yes abuse can’t happen in love. But bad treatment is subjective. Sometimes you have to say no to your loved ones. They might consider it bad treatment or “you don’t love me” but it might be just a necessity or inability to compromise. My dad thinks every time someone says no to him and doesn’t do what he thinks people (family or friends or anyone else) should do, it’s bad treatment and lack of love. But I don’t think so. Not every wish or demand could be met. It doesn’t mean there is no love.
