How to get her to trust me again?

I lost my girlfriends trust.
nothing too major.
but she doesn't trust me now.
she has good reason to have lost some trust, but i want to get it back.
the first thing i did was shared my location with her indefinitely. (via iPhone on my own will. It was my idea)
i can buy her ballons and flowers, but that's not really doing much to solve the actual problem at hand.
i know its going to take honesty and time to repair this,
but my main concern is, i don't want it to seem like i'm ignoring the problem in the mean time.
how do i do that?

You need to earn her trust back. Sure it will take time but it will be worth it. Say you are sorry for loosing her trust and it won't happen again. Hope this helps. X

Make sure she knows how you feel and that you want to fix the problem.
