Send a Mid-Autumn Festival blessing message to your ex-boyfriend, will it make your heart tangled? If he doesn't reply, does that mean he still cares?

If it's an ex-boyfriend, why send him a message? You care about him and can't let him go! You didn't want to get back together with him at first, or I didn't think it was necessary to send this message. Maybe you just sent a timed message. Maybe it's not like this in his place!

There are two possibilities for not returning messages. First of all, I don't know how to reply you! Second, I just don't want to talk to you!
