Hi Peter!
I feel like maybe it’s a good thing that you broke up with her. Nobody is perfect and you were following your heart at that time. Do not feel guilty about anything. You can’t MAKE anyone doubt themselves. She is doing it all on her own. Sounds like she is having some inner confusion herself, that was only brought out by your actions. It was already in there, laying dormant, and sometimes things happen in order to help oneself or another deal with certain “inner demons” that need to come out and be healed. Nothing happens by mistake in life and especially this. Have confidence in your decision at that time to break things off, and approach this situation with love, only love. But try not to bring toxic emotions of guilt into the mix. We’re all on this earth learning and living through experiences just like this. It’s what we’re here for! Send her love and if you wish to try to mend the relationship, maybe refocus on why you broke it off in the first place. Perhaps, that’s where the wisdom lies.
