He agreed to exclusive then reactivated his profile: what to do

A reactivated profile is ambiguous in a specific way. It tells you he opened the app, and it tells you his account is visible to other people again, but it doesn't tell you whether he swiped, messaged anyone, or had any intention of meeting someone. Two weeks is long enough that a person who was truly done with apps may have forgotten about the account entirely, and also long enough that someone testing the waters would have done more than look.

What matters more is the rest of the picture. Has he been as present in your texts as before? Did he bring up plans, or go quieter? When you two talk about the future, does he sound like he's still in it? Those signals will tell you more than the profile. If the rest of his behaviour is steady and the reactivation looks like a forgotten setting, you're probably dealing with carelessness. If the rest has pulled back, the reactivation is one more piece of evidence, not the whole case.

The reply needs to name the thing that was agreed. Exclusive means no active dating, and that's a specific promise, so talk about it that way. Mention the agreement and the date you made it, and say what it meant to you in one clear sentence. Don't list everything you're feeling. One sentence about what you expected, and one about how seeing the profile landed, is enough.

Then ask him something he can actually answer. 'Did you reactivate it on purpose?' works better than 'why did you do this?' because it gives him a plain fact to respond to. Leave room for him to say he forgot, or he was checking something, or he's not clear on what exclusive means to him. You want to hear his version before you decide what it means.

Send the message at a time when you're not already spiralling, ideally earlier in the day rather than late at night after you've been scrolling his profile. If you send it while still angry, every reply will get read as a confirmation of your worst guess. Give him a reasonable window to respond, often a day, and don't send follow-ups stacked on top of each other.

If he answers with something clear and reasonable, you can talk it through. If he gives a vague answer or deflects, ask one more direct question and see what happens. If he doesn't reply at all for a couple of days, or replies with something that makes the agreement sound like it was never serious, you have your answer about where he stands. At that point, decide whether the relationship can continue on the terms you agreed to, and act on that decision rather than waiting for another signal.
