2. You tell him, “I won’t be able to message you right away,” but he can see you’ve read his messages
“I get suspicious and think, ‘Is she with another guy…?’” Even if you take care to tell him in advance that you won’t be able to reply, he could still end up getting suspicious. If you explain the real reason you can’t respond and tell him roughly when you’ll be back in touch, you can avoid any hassle.
