Stuart,
I can feel your pain and I am so sorry that you are going through this. It is an awful story and I know it seems like the end of the world but tomorrow is another day… and you will find happiness again. You have to trust that Becky was not the one for you – and be relieved that you found out early in your life as opposed to years from now. I know that doesn’t make it easier but it will get easier. The next few months will be hell – but it does get better. Trust me!
I was with my husband for 20 years. He was my best friend. We were inseparable and then one day something changed. I too found his phone and discovered grossly inappropriate texts to another woman. I was blindsided and shocked. I wanted to stay in bed all day, every day but I couldn’t. I have kids and so do you! I had to function as best as I could and I tried to be kind to myself. Days where I couldn’t go to work – I didn’t. If I couldn’t make dinner – we ordered in.
Eventually I got through it and now I am on the other side and couldn’t be happier. My husband did me a favour that I could not see then. I promise you that you will find someone who will treat you the way you deserve to be treated. It is just going to take time for these wounds to heal.
My best advice is to find a great therapist and do the work now. You will be so much ahead in the long run!
