Because I've been jumped on before, I would like to set a disclaimer, that this is my journey and I am proceeding in a way that I feel comfortable with through this nasty mess. If it does not fit your style, then that's fine, I'm just talking about what has been working for me.
I'm almost 4 weeks past DDay. I was about blind with anger and hurt when I found out (affair was for 7 months almost 3 years ago). I confronted WS almost immediately. I think his response was what has helped me along the most. He's been completely honest, even offering additional information I didn't know. He has sought out counseling on his own and has really taken an inner look and decided he needed to change. He talks to me about what he's doing. Some days I want to listen and hear, and some days I do not. For me, I talk to him ALOT about what I'm feeling and how I'm feeling. I talk about how I feel about the future and I ask him questions about the past. I told him up front that I was going to try not to be nasty, but this will be an emotional journey for me and he really needs to understand that and be okay with it. He's always been the one I talked to (even if it hasn't been totally mutual), so I wouldn't know where else to turn anyway. When I'm angry, I tell him and I tell him how much I hurt and how much I hate him for what he did. He doesn't come back at me with anything other than understanding. Sometimes he tries to say sorry, but I told him he's not allowed. He absolutely understands that his family is on the line. On the flip side, these conversations about my anger aren't all the time - we have lots of very level, but deep conversations.
I am a person of faith. I have been through struggles much more devastating than this (not at all to diminish the devastation an affair causes) and my faith has brought me out in a better place on the other side. I pray alot and I ask God to give me strength and to take the pain or anger or sadness. It works for me. It may not be everyone's solution, but it has really helped me to level my feelings.
Because WS has sought council and because we are talking openly, I'm making ALOT of discoveries that I wouldn't necessarily make so soon otherwise. For example, one of the things that WS has done since before we were even married (I just learned about it after D-Day) was to give his 'woe as me' conversations to other women for validation/vindication of him being right. This is the exact behavior that eventually led to his affair. When we first met, we had a great connection and we talked about EVERYTHING and we communicated really well. As our relationship moved on, we stopped being able to communicate because every conversation was him getting really defensive and me feeling like the wicked shrew by the time it was all said and done. This was totally because he had these other women, who only heard his side of our relationship, telling him how wonderful he was and how wrong I was. Our conversations had no chance. It was really helpful to me to realize, this morning why we stopped being able to communicate. That lack of communication is the major downfall in our marriage.
Another thing about his affair that really hurt me was his notes back and forth with the OW. They could have really been copies of what we wrote when our relationship started. However, this am, I realized that I'm the only relationship he's really ever had that hasn't started by this need for vindication. We became friends while we were both with other people, but our relationship grew because we were good for each other. He was recently divorced and dating someone I knew. The person he was dating was just all over his ex (she's no mean and nasty and he's so right - vindication for him). I always encouraged him to bury the hatchet and move on without anger. When you have feelings for someone else (even anger), you have feelings for them. At one time, they loved each other enough to date for 9 years and then marry, so she can't be all bad.
My worst pain came last week. We were on vacation with our family and he mentioned something that just hit me in the gut with 'He had sex with another women'. I was completely ticked at him for the rest of the trip. I just wanted him to disappear and I did not want him to talk to me or be near me. When we got back, I took a deep breath and explained where I was. It was , by far, the most hurt I had felt up to this point. I explained that I wasn't sure I could stay and keep having these triggers. That was Saturday .... today, I made 2 positive discoveries and I see a step forward. I think it's a ridiculously long journey.
