Pup, I refuse to give her the time of day if she's ignoring my direct questions, or greetings. I just kind of snicker inside that it's unfrickinbelievable that she can be that way. I mean, she has done this and I don't care how bad she makes the marriage out to be before her affair (which is BS as anyone who knows us knows), nothing I've done deserves this, so I refuse to engage her.
H4U,
The problem with responding to her disrespectful and rude comments or actions with SILENCE, rather than calling her on them, is that she can easily mistake what you feel is "quiet detachment" with "fear," which feeds her already-strong sense of ENTITLEMENT.
I'm not saying it's fear, but I'm saying SHE can mistake it for such.
Now, NO ONE wants to have to go around in constant conflict, and I didn't either, but what I AM suggesting is that if you'll mix in even 10% boundary-establishing darts like the ones I suggest above, then you can still refuse to engage her the other 90% of the time and your message will have been received.
In fact, I'd be willing to bet that after you do it just TWICE, she will never ignore you again. Wanna bet???
