A MM I like sent a text message late at night saying that she couldn't sleep. Is she hinting at me?

It's possible, but sometimes it's because of boredom

It doesn't hurt to chase after it.

But some girls are like this,

When she needs you, you can kill boredom for her, or many other situations as long as you are worthy of her use.

But if you chase her and you want her to be your girlfriend, she will take a step back immediately.

So a woman's heart is a needle in the sea ~ ~
