Whether developing feelings for someone else while in a committed relationship constitutes cheating is a complex and subjective matter. The definition of cheating can vary between relationships, and what may be considered cheating to one person might not be the same for another. It depends on the boundaries and agreements established within the relationship.
In some relationships, emotional connections outside the partnership, especially if they involve romantic or intimate feelings, may be considered a breach of trust. In other relationships, there might be more openness to acknowledging that feelings can arise for others but committing to handle the situation honestly and responsibly.
Telling your current partner about the situation and breaking up with them immediately after realizing your feelings for someone else is certainly a responsible and honest course of action. It shows respect for your partner by not hiding the situation and taking steps to end the relationship if you feel it's necessary.
It's crucial to communicate openly and honestly with your partner about your feelings and the reasons for ending the relationship. This can provide closure and allow both of you to process the situation in a healthy way.
In any relationship, it's essential to be aware of your emotional boundaries and engage in open communication with your partner to ensure that both of you are on the same page regarding what is considered acceptable behavior within the relationship.
Every relationship is unique, and if you find yourself in a situation where you're developing feelings for someone else while in a committed partnership, it might be helpful to have an open and honest conversation with your partner about your feelings and work together to find a resolution that respects both of your needs and emotions.
