Jolu,
I'm new here, too. Your story sounds similar to mine. I have also come here looking for ideas and ways to help me move forward and stop letting the past haunt me. There, I cannot offer suggestions, but I do understand. Know you are not alone.
You mention that you H is in counseling. How about you? You didn't imply that but I bet it would be a great outlet for you, and perhaps offer guidance to resolution. How about MC? My H wouldn't commit to going and then refused to contine anyway. I think it's a good sign that your H is still going.
Trust is so very hard to rebuild. My snooping has drastically decreased, thankfully. His lies fed my belief that snooping was justified but really, I ended up feeling badly about myself b/c my behavior was going against my virtues and integrity. Think about that. You are already feeling down, and feeling badly about yourself does not help. My H has been trying to earn the trust back, and I am trying hard to be open to let him. Things do seem better, but I am struggling with reminders...so many things provoke painful memories. That is what my hurdle is right now. It's difficult to keep it to myself, and not project my frustration and feelings onto him.
I'm trying. I keep trying. I have not read everything offered on MB yet, but I printed out a whole bunch of it, and have told my H that I would like us to peruse all the information and do what we can to keep this marriage together. He is all for the latter, though he lacked much enthusiasm for the former. He did agree though. I will credit him there. We're both trying to give and understand and support each other. I remind myself of that positive thought when I am feeling overwhelmed by the past and feeling low.
It is a destructive cyclical quandry being fully aware that some behaviors are pushing away any progress but feeling too weak and helpless to control it because you are so full of grief and anger at times. I do understand. Try to keep positive thoughts. SGE
