Sorry your family is going through this but...

Maybe the woman didn't know about his family when they started dating?

I know adulterers suck, but...

Sometimes the other party doesn't know the truth, and then they "fall in love" or whatever...

It's really his fault, more than hers.

I know you're angry and hurt but...

Shouldn't let it bring you down to being a nasty hateful vindictive person. Is that who you want to be?
Is that who you want your kids to see?


You'll get through it.

...love and light to you family.
