I’m not sure what’s going on with my ex? Answer and I’ll answer 1 for you!?

We broke up 4 months ago and didn’t text for 2 of those months. Even after we’ve barely texted. About a month ago she texted asking about something she got me for my birthday back if I wasn’t using it. I took that as a hint she wanted to give each other’s things back and when I asked she said she wasn’t ready. I saw her for the first time at our college last week and she practically speed walked away. The first time we broke up we got back together but she said maybe we should have waited longer before getting back together. Idk if she doesn’t want to give each other’s stuff back or talk now cause she wants to get back together or if she’s still getting over the break up. What do you think?
