No, toxic relationship is defined by having your boundaries be crossed often in a relationship. If you're cool with an open relationship, ure cool with an open relationship.
The only thing is to communicate well with ur partner since open relationships and non monogamous relationships have different sets of regulations based on the people in the relationship!
Maybe one person is fine with not being told they're seeing someone else while another person would preferred to be told such, etc.
Take this manga and how Aimi sets his boundaries up-front! That's an example of clear cut communication!
Are you already in a toxic relationship if you agreed to be in an "open relationship" ?
