Questioning marraige

on mothers day, everything went well, we went to my moms house for a nice brunch, hung out, went to a awesome concert......but all of that was over shadowed by the abuse i went through. we were playing around at my folks, i cannot stress "playing" enough. until she got pissed and struck me. this is nothing new, she normally hits me on a daily basis. However, this time she hit the top of my shoulder. i think destroyed my rotatorcuff, i might get surgery.
