You found out that your girlfriend cheated on you. How should you behave?
Steps
Step 1. Evaluate your relationship
Do you believe that your relationship as a couple can be defined as healthy?
Step 2. Evaluate your role
No man forces his woman into infidelity, but perhaps you may have helped create a frail relationship, leading her to think she was worthless. Maybe you made her feel neglected or unwanted.
Step 3. Evaluate his character
Put aside your feelings for her for a moment and answer a question: do you think she is a reliable person in general? Do you think it can be defined as a mature person?
Step 4. Find out if the episode of infidelity could recur
If she doesn't seem willing to make any changes to her behavior to prevent the situation from happening again, perhaps the best thing you can do is end your relationship.
Step 5. Reflect and find out if you are able to truly and completely forgive her
If not, then you should break up your relationship. Do not choose to stay by his side while still feeling resentment for his past actions.
Step 6. Ask her to show you her love for you
After your forgiveness, she will need to be willing to put all her effort into repairing your relationship, otherwise she could make the same mistake over and over again.
