Not in answer to your questions, yes, and as far as anyone can be.
Why, well we were miserable, both of us, and neither of us could see any way out. It was an escape.
Will it ever happen again, well perhaps, who knows, the difference is I really don't think it will because DH and I after many years together, and much upset are finally happy. Genuinely happy. Everything about our relationship has changed, and everything about us as people has changed.
I have found myself, my self confidence, my self esteem, and I finally like myself. I've relaxed, let go and started to enjoy life, and stopped striving to be perfect. I am who I was before I married when life was easy.
DH has started to talk, about anything and everything, the big and the small. He shares the ups and downs of his day at work, he admits when things are getting on top of him, he no longer sulks, he is no longer selfish or self absorbed and really does put his family above everything. I love him for that, and I appreciate him in a way I never did before.
How did we get where we are, well we separated and I filed for divorce. I honestly think that is what made the difference for us. The whole situation became very real to DH. It was no longer something he could sweep under the carpet, or even control. It made him think and it made him talk.
In some ways his affair was the best thing that could have happened to our marriage as without it neither of us would ever have opened up properly. Once we were no longer together and the pressure cooker atmosphere was gone we were able to do just that, and become really good friends.
What I'm saying is you have to reach a place where you know you can be happy on your own before you know you can be happy together. If you don't there is a risk you will stay for the wrong reasons, and whatever it was that lead to his infidelity will reoccur. Getting past an affair is hard. Very very hard. 17 months on I still have black days. I don't think these will ever go. What keeps me here is the knowledge that although he makes me happy I don't need him to make me happy. I stay because I want to, not because I am scared to leave.
