I Have Complicated Feelings

I have a crush on a boy for two years. I have a crush on two girls since last august. I'm in a relationship, but i'm not happy. I constantly kept getting hurt by him. And he says he sorry all the time ,but never means it. He keeps pushing me away. I've been with him for almost four years . And i think the love i had for him is fading. It feels like i hate him,but still have love for him. I really am really lost and need guidance
