I sent him a short message this morning, but I haven't replied yet. Should I keep sending it to him? Still ignore him.

The problem you encounter is an eternal problem for everyone or lovers. In fact, it is entirely up to you to send it or not.

Because a person's feelings for another person, only the parties can understand, sometimes love deeply, you will forget how much you have given. If the other party doesn't reply, you can't help sending a second message. I didn't understand it before, but now I may change my mind a little.

I don't rule him out. He is very busy, but I think anyone who is busy can send a second message when he is free. If there is no response, don't continue. There is no such humble waiting. If you are important, he will reply to you as soon as possible and tell you the reason. This is the normal reaction of a person in love.

good luck
