Is there a way to tell if a girl has a boyfriend?

A girl who is seeing someone often keeps her availability fuzzy in a particular way. She'll say she's busy, mention a group or a friend's birthday, and avoid naming a day. The tell is not the busyness itself, since plenty of single women are busy. It's that the plans stay vague even when you offer specific times, and she doesn't seem to mind that you noticed. Single women who are interested usually either pick a time or propose one, because they want the meeting too. Take note of whether she engages with your suggestions at all. If she keeps circling back to chatting but never moves toward a date, you have a read on her interest and possibly on her situation.

Don't over-read a single sentence. Look at the pattern across several days of messages. One mention of 'my bf' in passing, or one awkward silence after you ask about her weekend, tells you very little. Three or four small signals pointing the same way tell you something real.

The clean way to find out is to ask about her life in a way that gives her room to bring it up. Questions about what she does on her own time, who she spends weekends with, or what she's looking forward to will often surface a partner without you asking the question outright. If she mentions someone, you'll hear it in how she describes them and what she does with that person, not just in a label. You can also keep your own life visible: talk about your plans, your friends, your week. That makes it natural for her to share hers, and it signals you aren't asking for a report.

If she still stays vague after a few open questions, that is an answer too. Respect it. Pushing for a direct yes or no tends to end the conversation, and if she is taken, you want to be the guy who was easy to talk to, not the one who made her uncomfortable.

Once you've got a feel for the situation, the most useful move is usually a specific invitation. A concrete plan does two things at once. It tests her interest in meeting you, which is the real question, and it forces the situation into the open without an interrogation. A single woman will usually say yes, suggest a time, or tell you she's not free and offer another day. A woman who is taken will often go quiet, get vague again, or say she's already got plans without offering an alternative. Either way you learn what you need.

At that point, stop collecting evidence. If she says no or goes silent after a clear invitation, that is enough. Keep the door open politely if you want, but don't spend more energy trying to prove she's single. Your time is better spent with someone who is actually available.
