Getting back with ex, yay or nay?

Okay so my ex and I broke up november last year, and it was a mutual break up as I had really bad anxiety and it messed with the relationship. But since then I did intense therapy and now my anxiety is almost 100% gone but my ex and I have started talking again and I'm seeing him tomorrow. We started talking today and he made me smile just by being his witty self! So just wonderinf, if it wasnt a bad break up and it was mutual and he was never a dick about it... Yay or nay to being together again sometime in the next couple of months..?
