Mostly good, I have a potential issue with this section:

Ask direct questions .
If you suspect someone is lying, remember that you are entitled to the truth. Don’t be bullied into dropping it until you are satisfied.

If you only 'suspect' the person is lying but have no evidence, don't badger them about it and put the thumbscrews to them until you torture them into 'admitting' what you've already decided to be true.

Sure, don't "be bullied" into forgetting about it - if you suspect, go ahead and watch for further evidence. But don't "be the bully" either - excessive suspicion without good reason can drive away an innocent partner faster than you can say "liar, liar, pants on fire."
