Love is the most dangerous of all emotions. It offers sub-emotions, mostly happiness, but sometimes anger and sadness. It comes in many forms: love for your parents, love for your friends, and love for your significant other.
My experience with love for my significant others hasn't always been great. My current boyfriend is wonderful. He treats me like a queen, with respect and overflowing love. However, when I was 18, I was blinded by the acid of toxic love.
He told me he loved me, but he told me I would be prettier if I lost a few pounds. He told me he loved me, but he told me I'm more fun when I'm drunk. He told me he loved me, but I would look hideous if I cut my long, red hair like I wanted to for years. And again, he told me he loved me, but he decided I wasn't good enough and he slept with some random sorority girl.
I thought I was happy. He had me under his sick spell, thinking I needed to change for him. After I tried starving myself and constantly drink to be fun for him, he woke me up one morning to kick me out to the streets. We never argued and he never laid a finger on me. But after he broke up with me out-of-the-blue, I felt as though I was the problem. He would text me, taunting me with fake apologies and fake "I love you"'s. He made me feel as though I was the problem for two years after.
I don't regret going through that hell-hole of a mentally abusive relationship. In fact, I matured from it. I learned that I was not the problem. If he could not see that I'm beautiful just the way I am, then he doesn't deserve me.
Abuse doesn't have to be physical. Pay attention to how your significant others treat you and leave if you're not treated like the true king/queen that you really are.
