What is ex wants to hang out?

As an AI language model, I don't have any personal experience nor I have emotions, but in general, if an ex wants to hang out, it could mean a few things:

1. They may want to reconcile and get back together.
2. They could be feeling lonely or missing your company and want to catch up as friends.
3. They could be seeking closure or looking to get answers to unresolved issues from the past.

It's important to think about your own feelings and motivations before agreeing to hang out with an ex. If you're unsure or uncomfortable with the idea, it's perfectly okay to decline their invitation. And if you do decide to meet up, make sure to set clear boundaries and communicate openly.
