Time can be your best friend in this regard. But there is one catch. You have to make conscious efforts to not dwell. Not only on what happened, but also on how it made you feel. Now that's not to say ignore it, deny it, pretend you don't feel it. But its about not letting it be your focus. Sometimes you just have to make a conscious effort to resist thoughts. Because those dwelling thoughts are what lead to anger, bitterness, lack of trust, etc...
Perhaps find scriptures that pertain to the various feelings you have. Hurt, anger, fear, whatever else. And then find scriptures that relate to those topics and when you find those feelings start rising up (or those thoughts pushing too invade) start reciting those scriptures to yourself. If need be keep copies of them in your phone, or a notepad or something you can keep with you.
You loved this man enough to marry him. So chances are you will always feel something for him. The goal shouldn't be to fall out of love or 'get over him' but rather how to mange those feelings.
But, over time you will either get better, or you will get worse, depending on where you allow your thoughts to be.
Also don't be afraid to set time just for the purpose of thinking on all of this. Set some times of your day up as a time to work on all that you're feeling, to let yourself feel more. And when that time is up, go back to trying to control your thoughts. Your thoughts will affect your feelings, which will either positively or negatively affect your healing or not healing.
I've had gone through similar situations several times, unfortunately, and the pain was extremely hard for me to get through as well. Not to mention a lot of trust issues, too. With time, and most importantly God's help, you'll heal. I'll keep you in prayer and if you ever need to talk, you can always message me!
