I'm sorry you struggle. I'm also sorry she chose to cheat on agreements rather than renegotiate or end agreements with you cleanly first.
I don't know if this helps you any.

I do know that poly is not "cheat proof." One can also cheat on their poly agreements. It's not the mono-ness or poly-ness of the relationship model but the character of the person that helps them keep their agreements. One must have integrity -- where their word and actions match. If they say one thing but do another... it's hard to trust them at their Word.
If she cheated on previous agreements? I am guessing those were deal breakers. Were they? If so? The old relationship is over.
What you are assessing now is if you want to start a NEW thing with her. The offer on the table? This new thing will be a poly thing, with her previous cheating affair partner in the network.
How do you feel about this offer?
- You have to assess if you are up for poly with THIS group of people.
- Because maybe you are not up for poly at all. With any people. Ever.
- Or might up for it, but not with these particular people at this time.
- Or maybe you are up for it with these particular people.
- Are you considering it because you like poly?
- Or because you are considering it in order to avoid a break up?
- Are you actually able trust her or rebuild trust with her?
- What behaviors has she done to make amends/demonstrate she is now trustworthy?
- Has enough time been spent on that?
- And if you are able to trust her.... are you WILLING to trust her? Or have you lost heart for this?
These are tough questions you could be asking yourself.
You've had a major ding. I would suggest getting your STD screens and taking a time out to think and soul search.
Not just leap right into a new thing/new relationship model.
Is setting boundaries like "no sex" too harsh?
To me, boundaries are for you to make to keep YOU safe with consequences for YOU to do.
If you mean "Is it to harsh to tell her I don't want to share sex with her right now?" It is not harsh. That is your body and
you pick who you share it with and when. She's not entitled to your body. You can have a boundary of "I don't share sex with people who have cheated on me. I need to run STD screenings first before I can even think about sharing sex with them again." That is a line in a sand to help keep you safe, with an action YOU can do.
If you mean "Is it too harsh to tell her no sex with the other person?"
Well, you could ask her to refrain. But if she's recently cheated on agreements that asked her not to a take up with other people, I'm not sure how this is a different agreement. Plus do you want to be policing her behaviors?
You do not reach personal emotional equilibrium within by managing people outside you.
