Dating my Ex?

I broke up with my ex in July, and we have been best friends ever since. I feel like we are getting to the stange where we miss each other and want to be together but don't know if we should! He's even started saying the cutest things and holding my hand when we are walking around! He always shows so much love, I don't know if I should try again with him or forget about it? 😔 
May I also add, we are friends with benifits! Which is why I think we started falling for each other in the first place!
