What does it mean that girls don't reply to text messages after drinking?

I think you should give up, because you said you have known each other for a long time. For so long, he didn't find you like him. I think he has found out, but he thinks you are impossible, so he doesn't want to embarrass everyone.

The situation now is that you told him the truth after you were drunk, and he didn't reply. The next day, you said he would reply to something else, so his idea was to ignore the previous events and pretend that nothing happened.

This expression of a girl is usually a very tactful refusal to you.

After all, you have known each other for a long time and are good friends. If he refuses you directly, you may not even be friends.

But now that everyone knows the refusal tacitly, they can still barely become friends.
