Kimba, welcome to SI. I'm so sorry that you find yourself here, but it's a great group of people.
In a nutshell, if he's doing the work:being transparent, remorseful, answering your questions it just takes time. Are you in IC? Are you guys in MC? Is he in IC? I am over 2 years out, and it still kills me. I still get sad. So what you are feeling is perfectly normal. The problem is not YOU! You had your trust broken, and that takes a lot of time, plus hard work, for your WH to earn that back.
Sometimes I think time is the dirtiest 4-letter word out there. I have healed quite a bit, but it just takes......time. Be honest with him on how you're feeling.
