Aren't you tired of being treated badly?
You have the power to change your situation for the better. Changing is scary and painful, but staying might be even worse. There is a lot of help out there for women who reach out - Al-anon, services for abuse victims, therapists and counsellors, etc...
Keep coming back - you will learn a lot here.
Bottom line - nobody deserves to be abused. There is no excuse, no good reason for it, and no way you need to tolerate it one minute longer.
