I was once in a relationship just like that, except the abuser/abusee would randomly switch from her to me and back. In the end the ONLY thing we had was the sex.
And the sex was great, right up to the end, even when we wouldn't speak to each other otherwise.
But when your life veers from soap opera to opera (everything magnified, the sound too loud, the drama too overwrought), it just isn't worth it anymore.
Still, hang around for the sex until he becomes absolutely unbearable....
Beautiful photo, beautiful you.
