I did something last night that really helped me. I wrote down how many times I've been knocked down by Hs actions in recent months. For me it went something like:

Found out about the affair - processed and came to terms
he left - processed and came to terms
He came back and left - processed and came to terms
He came back and left - processed and came to terms
he told me about OWs sexual preferences - processed and dismissed from mind
found further lies - processed and dismissed
visited most days and talked about R - processed and dealt
found out back with OW - processed and ACTED
stopped visiting - processed and came to terms
stopped communicating - processed and came to terms
told me he would never live with me again - processed and came to terms
met to discuss split of assets - processed and acting on it

etc etc

Noticed a theme. I can cope. Now thinking " come on then, what's next, bring it on"

There are stages to this 'thing' Few us of get BD and then that's it. We get lots and lots of shrapnel thereafter. Look what we can cope with. Every one of us.
