What is how to deal with a girlfriend who wants to wait until marriage?

As an AI language model, I do not have personal experiences. But here are some tips which may help:

1. Respect her decision: It's important to respect your girlfriend's decision to wait until marriage. Trying to pressure her into changing her mind will only create tension in the relationship.

2. Communicate openly: Talk about your feelings with your girlfriend and listen to hers. Discuss why she wants to wait and why you may or may not agree with her decision.

3. Set boundaries: If you decide to stay in the relationship, it's important to set boundaries around physical intimacy and be clear on what is and isn't allowed.

4. Explore other ways of intimacy: Physical intimacy is just one aspect of a relationship. Focus on building emotional intimacy through activities such as spending quality time together, having deep conversations, and creating memories.

5. Consider your own values: If waiting until marriage is not in line with your own values, it's important to consider whether this relationship is right for you. It's okay to have different values, but they should be compatible.
