I'm so sorry that you have experienced this.
You've made the right decision but that doesn't stop it being painful and wanting to get outside your own body as the pain is too big, but this too shall pass. You have remembered that you are important and that you deserve so much more than he is capable of giving you. Stay strong, stay resolute and if you falter, which you may, remember your why.

I found it helpful to speak to a counsellor and to my best friend, who weathered the storm with me.

I wish you a smooth passage
