The only thing stopping us from getting back together?

I'm meeting up with my ex in a few days for the first time since the break up which was a month and a half ago. We've spoke on the phone and resolved our issues, both agreed to the fact we both made a few mistakes, she has said she misses me and that most of her wants me back... The only thing that's stopping her is she's worried about wether she'll look at me and feel the same after it's been soo long since we've seen each other...

I've played it cool, kept conversations short and been nice, and the vibes I'm getting are that we still connect and get on like a house on fire, no awkward situations or silences. Like she is, I'm also a bit worried and nervous about seeing her face to face after so long, wether I'll look at her and feel everything I use to, we were together for a year and a half...

Does anyone have any advice on things I can sort of do to remind her of the old days so to speak?

Any advice is appreciated
