Should you be suspicious if they won't meet after weeks of texting?

Pay attention to what she does with a direct suggestion, not to how warm the messages feel. Someone who likes you but is nervous will often say yes in principle and then go quiet when you pin down a day. Someone who is keeping you around as a text pen pal will keep the conversation fun, avoid any specific plan, and redirect whenever a time comes up. The pattern to watch is the gap between enthusiasm and follow-through. If she says she wants to meet and then never proposes a time herself across several weeks, that is information, even if she is not doing anything wrong on purpose. Notice whether she ever initiates the plan or whether all the logistics have come from you. Notice whether she gives reasons that change every time or a single consistent one. A consistent reason, like a busy job or a recent breakup she has not mentioned, is easier to work with than a shifting list of excuses.

A good reply names one concrete option with a day, a place, and a rough time, and makes it easy for her to say yes or no. Give her a real choice between two options, such as a Thursday coffee near her office or a Saturday walk in a park you both know. That tells her you are serious and removes the work of planning. Keep the message short and warm, and do not add a second question or a paragraph about how much you have enjoyed talking. Asking once clearly is more respectful and more informative than asking five times softly. Then leave the ball in her court. If she answers with a specific yes or a counter-proposal with a real time, you are moving forward. If she responds with another vague reply, you have learned the answer without having to argue for it.

Send the plan message at a normal time, when she is likely to be free to think about it, not late at night when it reads as a move. Mid-morning or early evening on a weekday usually works. Give her two or three days to respond before following up, since most people take a day or so to check their calendar. If she does not answer, send one short follow-up that references the plan directly, such as asking whether either option works. If that gets nothing, the silence is your answer, and you should stop. Do not send a third message, do not guilt her about it, and do not post about it. Close the thread with dignity and move your attention to people who are actually showing up. Stopping is the most useful thing you can do once the pattern is clear.
