sometimes just the other party unwilling to listen like streep's role who try to talk to her husband, and he ignored her needs, so she just took off. Not saying she was right, but there is always a cause. Maybe you are hurt deeply by what she did,But if it was not deliberate,iit was out of the rage, maybe you can let it go, although not easy but as you said we are all humans, we all make mistakes, forgive others is just like forgive ourselves . Anyway I hope it work out for you, after all having a family is always better.
