(((Celticghirl))), no one deserves to suffer abuse. You've done nothing to deserve to be hit. If it's safe to do so, start making and carrying out your plan to leave. Reach out and get help. The DV shelters and advocacy groups will not judge you; they know the cycles of abuse and what it takes for women to leave and leave safely; they understand why we make the mistake of going back to our abuser; they know why we finally decide to leave for good.
Please check out the links that bookwyrm posted. They have information about safety plans and leaving. Take it one step at a time. You don't have to look at the big picture of leaving him all at once. Look at step 1 of your plan and do that. Then look at step 2, then step 3, etc.
Keep safe. Wishing you strength and peace. Hugs.
