I want to talk to a colleague. I added her to a WeChat chat and sent a message but didn't reply. Today, I sent her a message asking if she would mind making friends.

Depends on the time interval between her and you.

If the interval is not far.

Chatting is very frequent

Prove that I'm still interested in you

If you ignore it

You can just tell her.

You have had a crush on her for a long time.

At least you fought for it.

I don't regret not trying.
