Hi Tyler, Welcome to Piecing! If your W is saying she wants to work things out that is a huge step to reconciling.. congrats!
You mentioned your negative feelings. That's going to be a big hurdle for you to overcome. I think most of us here struggle with anger and resentment over how we've been treated. Once we start piecing, it seems like it should be our turn to see changes in our spouse to help heal the hurt. Unfortunately, that doesnt happen right away and we still carry the burden of being the one who gives.
Do everything you can to not let that anger poison your R. I allowed it to ruin our piecing last year. I was so caught up in how much I'd been hurt, and all the things my H should be sorry for that I forgot what a long slow process piecing is and threw my goals out the window once he came home. We ended up separated again at my request. So, don't let the slow progress discourage you and come here to vent. WAS expects us to contine to "win" them back and it can be unfair.
