boyfriend

I have the most amazing boyfriend in the world. He's caring and smart and kind and will do just about anything to make me happy. I've never met someone who was such a perfect match and brought out the best in me. But, I'd been in really emotionally abusive relationship prior to that which led me to not have trust in anyone or think I'm not worth it. I know my boyfriend would never be the type to cheat or hurt me, but I still can't get over the feelings of mistrust and worthlessness from my last relationship. How do I get over that?
