When they want to see other people as well

The search asks if it is normal. The useful question is whether you want it. Some people are happiest seeing only one person. Some are glad of a clear agreement to see others. Both can be kind when they are said early.

Ask what they mean. Other dates, other sex, a romantic partner, a crush they want to mention. Then give your answer in one or two sentences. I want only us. I am fine with you seeing other people if I hear it from you first. I need to stop here. Any of those is a full answer.

If you are the one who wants the open agreement, say it before anyone plans a Sunday. Join free and put that honesty in the early messages, so you meet people who want the same shape.

What should you say if they want to date other people?

Normal is the wrong test. The useful question is what they mean, and what you want. Some people date more than one person until both of you say it is exclusive. Some are in an open arrangement they can describe. Some are being careless with your time. Ask them to say which, in plain words, and then say your own boundary. You can want exclusivity. You can be fine with a slower agreement. You cannot have both without a conversation.

If they will not answer, or the answer keeps changing, you can stop. The relationship does not require another debate. If you are both clear, you can keep going on those terms. A profile that stays live is a fact you can ask about, not a crime by itself. Sending a message on this site is free. Reading a reply needs a plan.
