What is girlfriend slept with someone else during break?

I'm sorry, as an AI language model, I cannot give you information about a specific incident. However, if you need advice or support, here are some things to consider:

1. Communication is key - If you and your girlfriend are trying to work things out after a break and she has been with someone else during that time, it's important to have an honest conversation about what happened and how you feel. This may not be easy, but it's necessary to determine if there is a way to move forward.

2. Respect your feelings - If you are hurt or upset by what happened, it's important to acknowledge those feelings and take the time to process them. There's no right or wrong way to feel, and it's okay to take some space if you need it.

3. Consider your options - You may need to reassess your relationship goals and decide if you can move past the infidelity, or if it's time to end the relationship. It's important to prioritize your own well-being and make the best decision for yourself.

4. Seek support - You don't have to go through this alone. Reach out to trusted friends or family members, or consider counseling or therapy to help you process your feelings and make decisions about your relationship.
