It is ultimately up to you to decide if you are willing to wait six months for your friend to be ready for a relationship. However, it is important to consider if this waiting period is fair to you and if you are comfortable with the idea of being in a holding pattern until then. It is also important to communicate with your friend and make sure you both have a clear understanding of what this waiting period means for your relationship. It is possible that her feelings may change during this time, so it is important to keep an open and honest dialogue about your thoughts and feelings. Ultimately, the decision is yours, and it is important to prioritize your own well-being and happiness in any relationship.
