Having a horrible day... just venting

Had another fight with narcissistic husband. He's been showing the fake love bombing and fake affection for the past three months. Really sucking up. Today was his breaking point. He found an idiotic reason to get extremely angry at me and accused me of cheating on him and taking advantage of him. Again. Out of the blue. It's a repetitive cycle.. he tries so hard to convince me that he loves me and he's not abusive anymore. It lasts for a few months. Then his true colors and hatred come out. First the anger, rage, accusations. Them the silent treatment..."punishment." Then he's back to playing prince charming. It's an absolute mind fuck every time. This has been my life for 27 years. God help me. I don't know what i did to deserve this life.
