The girlfriend I just introduced doesn't return messages at night and ignores me. She said that I am introverted and not suitable for me to find one. I just compared it.

Someone introduced you? And then she said it was inappropriate? Then divide it. The meaning is clear. I don't like you.

If you are serious, stick to it. After all, if she can promise, it means she has a chance. The purpose of saying this is to make you care more about her, spend more time with her and spend more time with her. This is what it feels like to be cared for.

Depends on your situation. If you can't make a decision, then I can't help it.
