Is it worth rekindling with an ex in my case?

Went out with an ex girlfriend two days ago and we went out to shop for some stuff and initially she didn't want to eat with me but changed her mind and paid for our meal. I felt that we both could be ourselves when around each other, after meeting for a while I feel that we could be together again

We broke up months ago due to communication issues and didn't contact each other for 1 and half months but now I'm taking it slowly with her, slowly talking with her even since she was the one that talked to me out of the blue. At the end of the day, I offered a hug and she accepted it. But is it worth to rekindle this relationship with her? if so, how do I do it?
