I like a girl and I sent her a text message to express my love to him, but she didn’t reply to me. I will also reply to me when I send other text messages to her in the future!

You said it too tactfully. No matter if she refused or accepted it, but you said you didn’t mean it at all, wouldn’t she be embarrassed?

So until a boy clearly says I like you, girls will not express their opinion.

So please send a clearer message! If she doesn't reply, but doesn't ignore you (and will reply to other text messages), it means that she wants to think about it, and you have to behave well~
