Chasing a girl recently. She is very busy. Sometimes I text her and don't reply. When I ask her out, she won't say no immediately. She just said what she was busy with.

Girls are usually like this! She was lying when she said she was busy! She didn't refuse you to ask her out, just didn't answer! So, at least she doesn't hate you! She may be testing your sincerity! You can't just call and send messages. Let's move! You should take the initiative to find her! You can invite the "matchmaker" out to play and have dinner ... Take her! Opportunities should be created and grasped!
