Your abuser probably tells you you're weak. Other people may have said things along those lines, suggesting that only a weak person would stay in an abusive relationship.

 Here's another perspective for you to consider:

    You already posses the strength and perseverance to endure & overcome these challenges as a result of your personal experiences, You must be!, only a strong person could endure abuse for as long as you've endured it. Now, it's your time to redirect that strength instead of using it to endure abuse, channel your energy towards recovery and new beginning. 

   Accepting & Grieving the end of your relationship is part of closure in an abusive relationship. It will hurt terribly, it always hurts when you separate from someone you love, even if they've mistreated you, unlike the abuse, the grief will eventually end. It's easier to endure pain & agony from grieving when you know it's temporary.

   Moving forward requires you to endure pain. It's up to you which kind of pain you choose — the kind that hurts for a while, and then fades replaced by a new opportunity for happiness; or the kind that just keeps hurting for the rest of your life. If you decide to leave, then every time you feel overwhelmed by grief, pain and sadness, remind yourself that you are already strong enough to endure this. You are strong enough to get through to the other side.
