What to do to get her back (Romantic Things)?

Im contemplating or not whether or not to get my ex back, we broke up on new years eve because i told somebody something i shouldn’t of and it got back to her. We’ve had a rocky past but i love this woman more than anything. I’ve been contemplating a break up but i just cared so much for her and still do and what i just need is an idea i can work with to try to win her over again. What are some romantic things you’ve done in this situation, i know where she works but its in a mall so id have to find her car but i just want to surprise her, its something i havent been able to do very well during the relationship.

I love her very much and circumstances of why we broke up are pretty deep, but i believe she is the love of my life, i just want to prove to her i apprechiate her and that i love her. The last we have broken up i got her back by making a SCAVENGER HUNT in this indoor mall she works in, that was pretty extravagant, i think i need something along those lines.
Rich A i have not cheated on her, i think she just feels we need to see new people, thats what scares me. I think if i see somebody else and she finally decides she wants to give it another chance ill be with that one person or vice versa.

I would never cheat on her, what my friend told her was just something i was thinking about. She wants space between us, I went to go see her to talk about this with no real hope as to what will happen, she just says she needs our space as if we were going to go on a break.

I dont know what more i can do, i guess i just dont want the pain anymore.
