You may be interested in one person while they are still dating several. If you have not discussed exclusivity, neither your hopes nor the amount of time you have spent together automatically establishes an agreement.
Ask the question directly
“Are you looking to date exclusively?” is clearer than trying to interpret response times or how many evenings they are available. Say what you want as well. This is a conversation about compatibility, not a competition you win by appearing least affected.
If you already agreed to exclusivity and that agreement was broken, the issue is different. Discuss the breach rather than allowing the conversation to be reset as though no agreement existed.
Decide what works for you
You can be comfortable with nonexclusive dating, prefer exclusivity, or decide you want to pause until the other person knows what they want. You do not need to pretend an arrangement feels easy in order to seem modern or confident.
Equally, asking for exclusivity does not require the other person to offer it. Listen to the answer they give, rather than continuing in the hope that enough good dates will quietly change it.
Keep sexual-health decisions explicit
Discuss relevant partners, testing, and protection when sexual contact is part of the relationship. The details matter more than assumptions attached to the word “dating.”
If your preferences differ, you can leave without declaring either person dishonest. If someone misleads you about an agreement, you can address that without needing to prove every private motive. Clarity gives you a decision; speculation mostly gives you more evenings spent checking your phone.
