Desperately wanting to heal

My husband and I are almost 9 months past the initial discovery date & just this past week had discovery #5. I'm just now finding out that he carried on sexual relationships with multiple women while we were dating and that behavior was carried into our marriage. I'm absolutely devastated and I'm really struggling to get past the fact that he has been unfaithful to me the majority of the time we have known each other. I'm wondering what ground we have to stand on? Any recovery work we have done to this point feels so tainted to me. I don't know if this is the last of the information. I don't know if he is going to be truthful moving forward. The future of our marriage seems more unclear now than it ever has. What I do know is I've made some huge strides in my personal healing and recovery process. What I do know is that I want to continue to grow and heal and find my own footing again. I want to control the things that I have control over - myself. I would love to take the Harboring Hope course and learn how to love myself for probably the first time in my adult life. AR has been such a blessing in my life and I want to learn anything and everything this program has to offer.
