She used to laugh at all my jokes but now just sends OK

When someone goes from engaged responses to minimal ones, something has changed on her end. Maybe the initial attraction has settled. Maybe you've told similar jokes three times. Maybe she's busy, distracted, or losing interest. The 'ok' isn't random. It's a signal that your current approach isn't working.

This is different from her being slow to text. A one-word response after you've made an effort means she's still reading and replying, but she's not giving much back. That's a real data point. It means whatever you're doing right now needs to shift.

A reply here has to do two things at once. First, it stops the joke cycle without shame. You're not apologizing or getting defensive. You're just pivoting. Second, it opens up space for something less one-directional. Instead of you performing and her reacting, you're moving toward her actually saying something.

This might mean asking a real question about her life or something she cares about. It might mean sharing something that invites her to respond as a person, not just as an audience. Or it might mean calling attention to the shift directly but lightly, in a way that gives her room to explain without pressure.

If she replies to your reset attempt with actual words, you've got something to work with. Take that as your signal to keep going, but stay attentive. If you reset and still get one-word replies, send one more message after a few days. If nothing changes after that, stop. Continuing to text someone who has checked out will only make it harder for her to come back later.

The gap between messages matters too. If you're sending jokes back-to-back, give her breathing room. Wait for her to text first. If she doesn't, that's your answer. The 'ok' isn't a puzzle to solve. It's information. Use it to decide whether she's worth pursuing differently.
