Rules speaks a lot of sense. I'm a year on and it really does feel like a new relationship, with the wonderful man I met and married, not the b*stard he turned into. The only reason it works is because he desperately wants it to, and I love him enough to let him try. He's sorry, disgusted with himself, and totally humiliated. He has told me everything, because he knows that if he doesn't I won't stay. For me part of the healing process was knowing there were no more secrets. It's the secrets and lies that hurt, not the sex. Sex is sex, and can mean nothing. The effort taken to conceal an affair is something else.
Anniversaries are hard, I've just been through them. The date I found out... the business trips where I knew he would stay with her... the date I filed for divorce.... the date I found out I was pregnant with a child conceived probably the day before he told me... Every single one of those dates has brought it all back, all doubts, the hurt, all of it. I've felt a bit haunted by it, and wondered if I should go, but the look of fear and resignation in his eyes when I talked about it tell me everything I need to know.
You can get through it, if you both really want to. It is hard though. I have the perfect life now. An old friend visited at the weekend, someone I haven't seen for 20 years, and I could see she thought I was the luckiest person in the world. Beautiful baby, loving husband, wonderful home... Sometimes it helps for me to see that, and remember I am lucky. The past is the past, and it will colour the future, but it doesn't have to dictate it. Marriages can survive affairs and come out stronger. Many don't (those are the ones you will hear about), some do (and largely you will never know).
