Quoting *Amo a Mis Nenas*:" okay. so when everyone agreed on an open relationship, it's fine to see other people if both parties ... [snip!] ... me out. but it was all in the moment. he was sweet outside of that, and him choking me actually turned me on a little..."
Wow. Okay... where to start with this. Domestic Violence is not okay. Period. Full stop. He put his hands on her to hurt her because he was angry. That is domesitc violence - it is abuse!
If two adults have talked about
adding some rough play or S&M into their relationship and consented to
doine something (like choking in your case) then that is a totally different situation and has nothing to do with abuse.
Also, she didn't cheat on him. They agreed to have an open relationship. They were both naive enough to think that there wouldn't be emotional complications or STD's but there were. They made a bad decision together.
She is not the problem. He is. He set her free and then changed his mind. That is fine - people can change thier minds! When you change the rules, again, they need to discus what happens next like adults. If he feels like her continued relationship is cheating then he can leave her - but he can not abuse her! There is NEVER an excuse for abuse!
