The constant where are you going? who is going to be there? and calling my friends to see if I am there. Not to mention now she spends more time on my phone then I do. But when I am on it, she is right there over my shoulder. How long does this last?
What if that lasts until the day you die? Can you be ok with that? She is your wife and she deserves to know where you are going and who you are going to be with, despite the fact that you have given her reason not to believe you. Whether you have had an affair or not, you should be letting your wife know where you go and who you are with. That's respect and transparency. I'm 4 years out. I still take pictures for my BH when I go out with my girlfriends. Not because he thinks I am up to anything, but because I never want to give the impression of impropriety. I never want him to have a reason to doubt me again. If I am proactive about my whereabouts and what I am doing, he never will have a need to.
So how long does this last? As long as you are willing. And when your not, you can most likely go your separate ways. If I had to guess, the reason she is still suspicious is because you haven't shown her there is a reason not to be. You haven't put the work in to fix yourself. I might be wrong, but unfortunately the tone of your post suggests that you are impatient.
This is going to take a long time and a lot of hard work on your part. Demonstrating any kind of impatience with the process will not serve you well. Show her you are trustworthy by working on yourself and being proactive with your actions.
