It is always tough to try and figure what to do. My separation this time is going on 6 months. We had a separation a few years ago. I worked and worked then, and she tried then, but fell short. We did reconcile, but not working on the issues together really hurt us. By not relaying a good foundation, this time it fell apart. We argued and fought, but still I feel we loved each other. I know I was willing to give my life for her if I needed to, as with my kids. This time seemed to happen so suddenly, within a week or two. finally, she asked me to leave. I discovered there was an affair between her and a friend of hers. For the past few months, I have been (if you have been on my other posts) trying to decide through prayer and fasting, what to do. My therapist, who is a christian, asked me this question, can you ever be with her again, and not invision what she has done, and who she was with. I honestly can't at this point. Infidelity is hard for me, it has happened in my family, and I dealt with it as a kid. I also dated a woman in my 20's who was cheating on me, and didn't know until after we broke up. So there is some history for me there. But that is my own personal battle there. I guess that each person must seek the answer from God in their own way, and then go from there. Personally I am seeking a divorce, and trying to get the custody of my 5 children. What may be my answer may not be yours. If, IF each party is willing to try and work through the problems honestly, then there is a chance for God to step in and work on your hearts. Of course, each party has to be willing to be honest with each other, and most of all themselves. My STBX is unwilling to admit to her unfaithfulness, along with other issues she has had. I will, and have admitted to mine. If you can't be willing to admit the problem, then there is no way to work to a solution.
ChristianMama, I hope for the very best for you. At the outset, it seems that you are both willing to work at it. Good for you, and allow God to work in your hearts. It is infinitely better to try and work things out. May God reach in both your hearts and minds, and provide a way of healing to work in your marriage.
God bless,
