What does it mean when a girl tells you about another guy?

The length and tone of what she says about him tell you more than the fact that he exists. If she says it in passing, with a shrug or a joke, she is probably giving you a status update and checking your reaction in a low-stakes way. If she goes into detail about him, mentions him more than once, or seems to want you to ask, she may be curious how you'll handle competition or she may be more into him than she is letting on. Her wording matters too. A line like 'he's kind of a lot' signals mixed feelings. A line like 'we're going again Saturday' signals momentum. Read the message as a whole and don't assume the worst from one word.

Also notice what she does not say. If she doesn't use exclusive language, doesn't mention plans with him as a commitment, and keeps the focus on the two of you, the situation is probably still open. If she mentions him in a way that makes it sound settled, believe that, even if it stings.

If she tells you about another guy and you respond well, the next stretch of conversation will show whether she was testing you or just being honest. What counts is whether she keeps talking to you normally. If she keeps asking about your day, sends you things she finds funny, and suggests plans, you are still in the game. If her messages get shorter, slower, or start to sound like polite closing lines, she has likely decided where you stand.

Don't try to fill that gap with pressure. A message asking whether she's still into you, or a long reply explaining how you feel, usually shifts the whole conversation onto your anxiety. Keep your own life moving, keep your messages light, and let her set the pace for a few days before you reach out again.

Timing changes how a message reads. If she tells you about another guy late at night and you answer right away with a long, emotional response, it looks like the news hit harder than you wanted to show. If you wait until the next day, respond briefly, and then move on to something else, you come across as secure. A reasonable window is a few hours during the day, enough to show you weren't stung by it, not so long that she thinks you went cold.

If she doesn't answer after your reply, leave it. Don't follow up with a second message about him or ask whether she's okay. One message is usually enough. If the conversation dies there, the connection was probably weaker than it looked, and you'll learn more from her next move than from anything you add now.
