This is a question for which there is no universal answer because every couple and every person has their own norms and expectations about what is acceptable behavior in a relationship.

However, it is important to understand that in a relationship there is a trust agreement between partners, which should take into account their feelings, needs and boundaries. If one of the partners feels that flirting with other women violates their boundaries or hurts or distrusts, this should be respected and discussed with the partner.

The key factor is openness, honesty and discussion with a partner. If both partners are open and honest with each other, they can discuss what is acceptable for them in a relationship and what is not. Sometimes, even if partners have different opinions about what is acceptable, they can find a compromise that takes both sides into account and strengthens their relationship.

In general, flirting with other women in a relationship can be acceptable as long as it does not violate the boundaries and trust of the partners and if it is discussed with and agreed between the partner.
