I can offer some general advice on how to approach this situation.
Give him some space: People react differently to arguments or conflicts. Some may need time alone to process their emotions and thoughts. Respect his need for space and give him some time before reaching out again.
Communicate calmly and openly: Once some time has passed, try to initiate communication in a non-confrontational manner. Express your feelings and willingness to talk about the argument calmly and openly.
Avoid jumping to conclusions: It's easy to assume the worst when someone deactivates their social media accounts or stops communicating. However, there could be various reasons for his actions, and it's essential not to jump to conclusions without talking to him directly.
Consider other communication methods: If he's not responding on social media, try reaching out through other means like text messaging, calling, or even meeting in person if possible.
Reflect on the argument: Take some time to reflect on the argument and your own feelings. Try to understand his perspective as well. This self-reflection can be helpful when you eventually talk about the issue.
Seek support: Reach out to friends or family members for support during this time. Talking to someone you trust can help you cope with the situation.
Seek professional help if needed: If you find yourself struggling with the situation or the emotions it brings up, consider seeking guidance from a counselor or therapist who can offer objective advice.
Remember that every relationship is unique, and communication is crucial in resolving conflicts. It's essential to approach the situation with empathy and understanding. If he continues to avoid communication or if the situation becomes concerning, it might be worth seeking professional advice or considering the health of the relationship.
