From what you wrote "...it's gonna take some time to regain her trust."
You must have done something that broke the trust, or she thinks you did.
It's up to her to forgive you and it's up to you to be trustworthy.
What's going on is you love her but you broke the trust.
I can't tell you what she will choose to do about it or what you should try to win her back.
If you give her some space, if you are sincere and trustworthy moving forward, you might have a chance. Hope it works out for you ! JUstin_Jackson
