She asked me to talk about it.

From my point of view, she is still angry about something before.

Think about it, you have reason to be angry, but she is also angry. And if it weren't for anger, there would have been rumors that you were living together. She felt embarrassed and said so.

In fact, I think the best solution is to ask her honestly without suspicion, so that it is possible to lay a good foundation for future marriage. Just tell the truth. Tell me everything you are unhappy about. Because your relationship is already very close, don't care, handle the contradiction well.

As for whether you want to be together on Valentine's Day or not, whether you want to be with her depends on whether she wants to be together.

In fact, as long as you live well in the world, you don't care for a day or two. Say "Love the right person, spend Valentine's Day every day"

Cheer up. Confession is golden. Grasp it well and stop being stubborn.
