Q: If you feel like the damage is irreparable, or that you cannot ever trust your girlfriend again, break up. Know that moving forward as a couple will be painful, and you may have constant reminders or triggers of the infidelity come up for you. Consider whether you can move forward with her, or if you will be better off breaking it off. Both are painful choices. It's not fair to your partner to lock down her life, to go through all of her private life (texts, emails, phone calls, etc) if you know you can never trust her again; it will be punishing both of you. If you decide to stay together, find ways to reconnect in new, meaningful ways. Perhaps you still love and care for each other but struggled to express it to each other. It is possible that other factors of life began to take importance over your relationship. Together, determine to contribute to the relationship in meaningful ways. Realize that it's not just the job of your girlfriend to make things new; you will need to contribute to creating a new foundation as well.

Forgiving your partner does not mean she gets a free pass, or that her behavior was okay. Forgiveness takes the focus away from the offense and acts to free yourself from the pain of the situation. You may feel like a victim or powerless after hearing the news of cheating; forgiveness allows you to reclaim power over your own emotions. Forgive your partner in a way that allows you to feel free from the powerlessness, to validate your own emotions, and then let them go.  Even if you decide to break up with your girlfriend, holding onto pain and hurt will not serve you. Let it go. For more information, check out How to Forgive a Cheater. Talk to your partner about what constitutes infidelity and create clear boundaries. While most people agree that sex is considered cheating, others may consider flirting, touching, kissing or intimate conversations cheating. Be clear on discussing boundaries with your partner. Some people choose to be in open relationships, which means that intimacy can be shared outside of the relationship. If you and your partner choose to have an open relationship, be clear on the boundaries of that as well. Cheating can still happen within open relationships, and trust is important. If you agree that the relationship needs work and that you want to stick with it but don't know where to start, seek counseling. You can attend couples counseling to help you ways to rebuild trust, find ways to cope with the betrayal, and build a new relationship together.

A: Decide whether to break up. Build a new foundation. Forgive. Consider relationship boundaries. Reach out for therapy.

Q: Love is not a manufactured emotion. If you've fallen out of love and its not coming back then perhaps it isn't meant to be. People fall in and out of love all the time, and though it can be difficult, there are not always explanations. Sometimes it just happens. By the same logic, however, sometimes your feelings will just spring up naturally, renewing love where you thought there was none. At the end of the day, the best advice is to follow your gut, be honest with yourself and your partner, and hope for the best.
A:
Don't force things.
