Are there any ladies who recognize the feeling of wanting to have a baby after a relationship crisis to make a fresh start?

I'm not proud of it at all, but I started an affair and feel incredibly guilty about it. I have everything I could ever wish for: two lovely girls and a very kind, caring husband who truly does everything for our family. He was so devastated when he found out; he said his world crumbled, he cried, and he couldn't sleep properly anymore. Now, despite the pain I caused him, he has decided to continue with me, but he still says he has an inner wound that needs time to heal. Trust hasn't fully returned yet, but as long as I reassure him that he is truly the only one for me and that I really don't want any contact with that man anymore, he's doing okay.

Now I also want a fourth child to make a fresh start for our family and to show him that I'm truly committed to him and our marriage.

It feels good to write this down. Does anyone relate to this or have they been in the same situation as I am now?
