Please advise if I get the chance to date with my ex?

My ex and I reconnected as of late. We message each other again and be a tease once in a while. Sort of like the time before we got together. To stop the story we consented to have a go at going out once more. We're going out seven days from now and I'm entirely eager to meet her once more, yet REALLY apprehensive as well. I don't comprehend why I feel along these lines. We've been as one preceding as of now yet I don't have the foggiest idea. Despite everything it feels like the absolute first time. Lol. Everything appears an unfamiliar to me once more. Anybody moved tips about out on dates with exes?
