Are we back together?

I was dating someone a few months ago, he broke up with me cause he had chronic back pain and said he needs to focus on himself. Recently he took me away for the weekend, and all our friends and his family were excited and surprised to see me. His brother asked me if we are back together, I just said we are friends, but he told my girlfriend that “we are figuring things out” I’m not sure what that means since we didn’t have a conversation with one another. Was it just a random thing are does he really want to give it another go?
