Good Morning and welcome to HealingWell.
Discovering infidelity, or deception by a loved one, creates a lot of uncertainty and anxiety. I am not sure what your problems are but perhaps if you step back and take a break from each other you will be able to focus on how to deal with your anxiety issues.
From time to time, our intimate relationships can become complicated and complex - full of contradictions and inconsistencies. Remember, you are in control of your life, look for ways to decrease your anxiety and take care of you first.
May I also suggest you look at ways to increase your selfesteem. Perhaps even see a therapist to help you sort through your feelings.
Again a warm welcome,
