As above what Adinva and dbmod said...

Also, it is great you are recognizing your part in the breakdown of the M. Do understand that while it is good to own your part and make the necessary changes you believe will help you be a better person, do your best to not beat yourself up over it.

Both you and your W played a part. You do not have to shoulder all the responsibility. And... you can only control you, so that's why DB indicates working on yourself as the focus...
