I can provide some general advice on the situation you described.
Communication is a crucial aspect of any relationship, and it's natural to want to stay connected with your partner. If you and your boyfriend used to talk frequently but haven't spoken for weeks, it's understandable that you might feel concerned or uncertain about the situation.
Before jumping to conclusions, it's essential to have an open and honest conversation with your boyfriend. Communicate your feelings and concerns calmly and respectfully. Express that you've noticed a decrease in communication and ask if everything is okay.
Keep in mind that people have different communication styles and need varying degrees of alone time. It's possible that your boyfriend genuinely meant what he said about not needing to spend every minute together, but it's crucial to establish a healthy balance that works for both of you.
However, if your attempts at communication are consistently ignored, and you have reasons to suspect that he might be talking to someone else, it's essential to address your concerns. Trust is vital in any relationship, and if it's being compromised, it's essential to address the issue.
Remember, open communication and trust are essential building blocks of a strong and healthy relationship. If you find it difficult to discuss your feelings or if your concerns persist, consider seeking guidance from a relationship counselor or therapist who can provide personalized advice and support.
