So long story short. My partner (31F) wants to start a relationship with someone she is falling for. This is a bit of a transition for me from the open relationship we have previously discussed and I think will require some work and compromise from both to make it work. Anyhow, we have always spoke about the fact that I would be her primary partner (we live with each and have been together 6 years). I feel strongly that she should communicate that with her potential new partner, what do you all think about this? Am I being controlling? Or asking too much? I can understand why this would be a difficult thing to say. How would you negotiate this?

We had an argument about this last week and want to talk about it this week and I’d love to come across a little more measured and controlled. She thinks I’m playing the ‘victim’ card as I agreed to an open relationship (but not polyamory). I can only really see it working if firstly I continue to work on myself and let my partner choose me. Anyhow I am committed in this relationship but also fully aware that we are at a tipping point. Oh and I’ve done all the reading / research and currently do therapy so definitely not going to let this shrink me.

Thanks for any meaningful advice or tips to how you have negotiated a new relationship.
