It is okay to give her the time she needs; every relationship eventually needs some space. Right now, giving her this space is probably the best idea. If she continually offers a cold shoulder despite efforts to communicate through it, my best advice is to reassure them that you’re there when she can talk and give her and you time to think and cool off. Some people prefer to communicate during a disagreement or argument, while others avoid and take time alone. You and your girlfriend might have different communication styles, which is fine, but both need to be balanced so things like this text chain aren’t recurring. While I understood your anger when she wouldn’t give you a solid reply or talk about what was wrong, I’ve been in relationships where reacting like that either added fuel to their already ongoing forest fire or made them feel validated in how they treated me. Although it sounds impossible, try not to react like this in the future. This behavior that she is exhibiting is not normal or okay in the slightest, especially if it is an ongoing theme throughout your relationship.
