What to do if he texts you about dating someone else casually
He just told you he's casually seeing someone else. Here's how to read the message, reply with your own position, and decide when to follow up or stop.
When a guy tells you he is casually dating someone else, he is usually giving you an update, not asking for permission. He may be trying to be considerate, since he would rather you hear it from him than from a mutual friend. The message tells you what he is doing right now, and it may tell you he is not planning to pause other people while you two figure things out.
A good reply does three things. It acknowledges that he told you, it states where you stand with that information, and it leaves the door open or closed on purpose. You do not need to match his level of detail or ask for a full rundown. You need to decide whether this is an arrangement you can live with or a sign you want something different.
How you respond also sets the pace. A calm, clear answer teaches him that you can be told things without drama, and it makes the next conversation easier. A reply full of emotion, or one that pretends nothing happened, leaves him guessing about what you want and leaves you guessing about what he wants.

He's giving you an update, not asking permission
Look at what he chose to include. He named the situation, gave a time frame, and used the word casually. That is someone describing where things are so you are not blindsided later. If he wanted your blessing, he would ask whether you mind, and he would sound unsure about the answer. Most guys who text this way have already decided, and they want to know how you will take it.
The context around the message matters more than the wording. If you two have been flirting, making plans, or acting like something is building, this disclosure may mean he is keeping options open while still treating you as a possibility. If you have been casual for a while and he is simply being transparent, it may be a reasonable check in. The same sentence means different things depending on what he has been doing with you.
Decide your own status before you reply
Before you type anything, work out what this means for you. Are you also seeing other people? Would you be fine with a casual setup, or do you want exclusivity? Your reply should come from that answer, not from how you feel about him dating someone else. Hurt is a normal response, but it is not a plan, and a reply written from hurt usually asks for something you do not actually want.
Once you know where you stand, the reply needs to acknowledge he told you, state your position in one or two plain sentences, and make clear whether you are staying in the arrangement. Avoid questions about the other person, because they turn his update into an interview and give him the upper hand. Keep the message about you and what you want from here.
Give it a day before you follow up
Send your reply in daylight, within a few hours if you can. A reply sent at midnight tends to carry more weight than you intend, and he may read it as more upset than you are. If you need time to think, say so and give a real window, like tomorrow evening. Going silent without warning reads as a message in itself, so do not leave him guessing about whether you saw it.
If he does not respond within about a day, send one short follow-up that restates your position or asks for a plain answer about what he wants. Do not send a third message. If he replies with something vague, decide whether vague works for you. If he keeps dodging a clear question, stop. Two unanswered messages on this topic already tell you what you need to know.
Why these replies fail
“Oh wow, okay. Who is she? Is it serious? How long has this been going on?”
It turns his update into an interrogation and signals that you are more invested in the details than in your own position.
“No worries at all!! Glad you're being honest, I'm totally cool with it haha”
It says you are fine when you may not be, which sets up confusion and resentment for later.
“Cool. Guess I'll stop waiting around then.”
It is passive aggressive, hides what you actually want, and makes him respond to a mood instead of a clear position.
Common mistakes
- Acting fine when you are not, then going quiet or cold a few days later
- Asking about the other person, what she is like, or whether it is serious
- Treating his message as a request for your blessing and giving it away
- Starting to date other people immediately to prove a point
- Sending a long emotional message at midnight that you have to walk back
Questions people ask
- Is it bad that he told me he's dating someone else casually?
- Not on its own. Telling you is a sign he is trying not to hide things, which is better than finding out later. What matters is how he is treating you now. If he is still flirting and making plans with you while seeing someone else, you have information about the setup. Decide whether that works for you before you respond.
- Should I tell him I'm upset?
- You can say how it landed in one plain sentence, without asking him to fix it or apologize. Naming your reaction and your position is enough. Avoid heavy statements you will have to walk back later. If you are upset enough that you want a different arrangement, say that directly instead of hoping he picks up on it.
- How long should I wait for him to respond?
- About a day is a reasonable window for a text like this. If he has been responsive all along and goes quiet after this message, you can send one follow-up after roughly 24 hours. After that, the silence is his answer. Do not spend a week trying to decode it.
- Should I start seeing other people too?
- Only if you actually want to. Matching him is a common reaction, but it usually creates a worse version of the same problem. If you are open to casual dating, say so and date on your own terms. If you are not, deciding that is more useful than building a rival plan.
