How to Reply When She Says She's Going to a Party Tomorrow Night

A message about a birthday party tomorrow is most often exactly what it looks like: she's telling you her plans. People do this when they're getting comfortable with someone. It's a small disclosure, a bit of her real life, and it doesn't usually carry a hidden meaning. The only real question is whether she's mentioning it because she's excited about it, because she's letting you know she's busy, or because she's softening a no in advance. You can usually tell from the tone. If she says 'should be fun' with some energy, she's excited. If she's flat and brief and offers no detail, she might be giving you a heads up that tomorrow's out.

It also helps to look at what's come before. If you've been trading messages easily and she's been making plans of her own, the party is just part of that. If she's been short on replies all week and this is the first thing she's volunteered, read it as a bit more deliberate, and respond with less pressure.

The party gives you something real to respond to, so use it. Ask one question about the event or the friend that doesn't require her to answer at length, something she can answer in a line or two while still feeling heard. Whether it's a good thing to be doing, a funny detail about the bar, or what she's wearing, any of those gives her an easy way to keep talking. What you're doing here is showing you're paying attention to her life, which is more attractive than any suggestion about meeting up.

Keep your own week out of it. If you have plans tomorrow, you can mention them lightly, but only if it comes up naturally. Leading with your own schedule makes it sound like a contest for who's busier. If you're free and want to see her, that's fine to say, but save it for a later message once she's responded to the first one.

If she sent this in the evening, don't wait a whole day to answer. A reply that comes many hours later reads as though you weren't interested, or that you were choosing your words carefully. Answer within an hour or two if you can, while the conversation is still warm. If it's late and you're replying the next morning, that's fine too, but don't send something long and intense first thing.

If she goes quiet after your reply, don't follow up that night. Give it until the next day. Tomorrow evening she'll probably be out, so expect little from her then. A good moment to check in is the morning after the party, with something light about how it went. If she doesn't reply to that either, let it drop for a few days and try again with a simple suggestion. If she still isn't engaging after two or three attempts spread over a couple of weeks, the message was telling you she isn't interested in building this up.
