Husband cheated, left, trying to DB

[SteveLW]

kech, most of the time you should ignore it. I would ignore the passive-aggressive stuff. Like him not saying goodbye, etc.

I think LITB is saying do not tolerate DISRESPECTFUL or ABUSIVE behavior. When he gets blatantly disrespectful or abusive then stop him and tell him he is welcome to come see his D but that you will not tolerate being disrespected. Again, this is for blatant disrespect. That he isn't talkative or "ignores" you, I wouldn't address that at all.
