It's understandable that you're feeling conflicted about your girlfriend's lie regarding her night out clubbing. The situation involves trust, fears stemming from past experiences, and the complexities of your relationship. Let's break down the key elements to help you navigate your feelings and consider the path forward.

1. Understanding the Context:

Your aversion to clubbing is deeply rooted in a painful past experience. Trust issues often arise when someone has been hurt before, and it’s completely valid for you to have strong feelings about this. Your girlfriend's decision to lie may stem from her desire to protect the relationship, especially given your previous breakup. She feared that the truth would lead to another separation, which speaks to her understanding of your sensitivities.

2. The Nature of the Lie:

Lying can be seen as a breach of trust, which is fundamental in any relationship. However, it's essential to consider the motivation behind the lie. In her case, it seems she was driven by fear rather than malice. This doesn’t excuse her actions, but it does provide context. For instance, if she had been honest from the beginning, she might have faced your initial reaction of hurt or anger. Her reluctance to reveal the truth indicates that she values the relationship and fears losing you.

3. The Impact of Mental Health:

You mentioned that your experience with OCD has made you more sensitive to situations involving trust and betrayal. It's commendable that you've sought therapy and worked on your mental health. This progress is crucial because it allows you to approach this situation with a more balanced perspective. Acknowledging that your feelings are valid while also recognizing that people can make mistakes is essential. For example, in therapy, you may have learned the importance of communicating openly about your feelings and fears, which can help in resolving conflicts.

4. Moving Forward:

The key question is whether this lie is forgivable. It ultimately depends on your feelings and the dynamics of your relationship. Here are some considerations:

• Communication: Have an open conversation with her about how her lie made you feel. Express your feelings without placing blame. Use "I" statements, such as "I felt hurt when I learned you lied about going clubbing."
• Trust Rebuilding: Discuss how you can rebuild trust moving forward. This might include setting boundaries or having regular check-ins about feelings and fears.
• Evaluating the Relationship: Consider if this relationship is worth the effort. If you both are committed to working through this, it can be a chance for growth.

5. Conclusion:

In relationships, mistakes can happen, and the key lies in how both partners handle them. If your girlfriend is willing to be honest moving forward and you both can communicate effectively, it may be possible to forgive her and strengthen your bond. It’s essential to give yourself time to process your feelings and decide what’s best for you in this relationship.

Ultimately, the decision to forgive her lies with you, but remember that every relationship has its challenges. How you navigate them together can define the strength of your partnership.
