The past is my problem i.e....I can't seem to get over the mistakes H made that broke my trust. I thought I had forgiven but can't seem to forget
This is such a tough place to be. It seems that even when things are going good, something happens to spark a memory, and brings back the pain. I don't think that any of us, at any stage of the game, are immune to this.
I'm sad to tell you that there is no "magic wand" that can be waved to take those memories away. Nothing that can be done to instantly relieve the suffering you feel. Yes, it can go away with time, but, more importantly, it goes away with a lot of work.
The work involved isn't so much in trying to forget the past, but in trying to embrace the present, and envisioning the future.
The one main thing that I've seen that works is to keep filling up your heart with things that help you to push out the "bad" things that have happened in the past. To concentrate on embracing the good things that are happening right now, and envisioning your hopes for the future.
This can be one of those "easier said than done" things, and will take a helluva a lot of effort. However, it does go back to the idea of "Forgiveness is a gift you give yourself".
What things might he be able to do to regain your trust? What could he do that would make you more confident that he really is trying to work on your relationship now?
