Give yourself time to process your feelings without rushing to make decisions.
Set Boundaries: Establish clear boundaries with your girlfriend regarding what you are willing to tolerate in the relationship. If infidelity is a deal-breaker for you, communicate that to her honestly.
Consider Professional Help: Given your girlfriend's diagnosis of BPD and the complexity of the situation, it may be beneficial for both of you to seek professional help. Individual therapy for her and couples therapy for both of you can provide a safe space to explore the issues in the relationship.
Understand BPD and Infidelity: BPD can be associated with impulsive behaviors and difficulties in managing emotions and relationships. While it doesn't excuse infidelity, understanding the condition can provide some insight into her actions.
Focus on Self-Care: Take care of yourself during this challenging time. Reach out to friends or family for support, engage in activities that bring you joy, and consider seeking your therapy to process your emotions.
Reflect on the Relationship: Take time to reflect on the overall health and dynamics of the relationship. Consider what you want and need from a partnership and whether this relationship aligns with your values and goals.
Consult with a Professional: Talking to a mental health professional can provide you with personalized guidance based on your specific circumstances. They can help you navigate through the emotions and decisions you're facing.
Ultimately, the decision of whether to continue the relationship or not is a deeply personal one that only you can make. It's important to prioritize your emotional well-being and assess what is best for your long-term happiness and fulfillment. Sometimes, seeking professional help can provide clarity and support as you work through these difficult choices.
