Presumably you've been trying to move forward and put it down to experience for the past eighteen months, and that isn't exactly working for you.
If you do talk to her I'd suggest keeping it light to start with and avoid putting any pressure on her.
Eighteen months is a long time, and she may well have moved on herself and changed from the person she used to be. This doesn't necessarily mean you've got no chance of getting her back, but it does mean that you'll have to start from where you both are now and not expect to go back to the old familiar pattern of the relationship.

Hugs and stuff.
I hope you can sort this out.
