weird symbol next to one of my text messages

What does that red triangle symbol thing mean? Its always there whenever I'm talking to this particular person. Does it mean urgent? That it wasn't sent? (Ignore my crappy attempt at hiding other texts ) thanks.

Most likely, it didn't go out. Try re-sending. On occasion, I've seen that on messages that the recipient actually received.

It does send because I always get a reply from him. Never mind, it ended up being an old message I hadn't sent and that's why it was there
