What is when your guy friend gets a girlfriend and stops talking to you?

As an AI language model, I do not have any personal experiences or emotions. However, it can be difficult when a friend starts dating someone and seems to prioritize their relationship over their friendships. It is important to communicate how you feel and try to make time for each other, but ultimately it is their decision and they may need space to focus on their relationship. It is also important to remember that friendships can evolve and change over time, and it is okay to let go of relationships that no longer serve you.
