How do we convince our friends that the person they are Seeing, dating, or marrying are definately not the one for them...have RED FLAGS coming out their arse...as words coming out their mouths. How do we convince someone that their partner, of a few months, has severe mental problems and is not healthy for you or your family, ie children? How do we Convince ourselves that the financial disaster, verbal abusive person we live has so many problems that we cannot be healthy with them? Rather, we convince ourselves, Quite easily, that 'they can only get healthy with Our Help', that we couldn't possibly live without them...
Denial, hiding the red flags, pretending they aren't as bad as they are...let's see a 28 year old male, dishonorably discharged, bankruptcy, arrested for assault twice, controlling to the max...majorly distinct extremes of emotions...can't remember the rest of them...how to convince yourself the man you want to marry and have a kid with is so Nice and Wonderful...that you Love, is your soul mate...blah, blah, blah.
Now, 17 years later Mom is now at wits end with a distinctly bipolar daughter with severe ADHD. She did not stay with the guy is one blessing. By 2.5 you could tell the daughter was off...and violent. Daughter at half way house...etc.

So, denial, avoidance, distancing from ''the reality'' at least from our view...we share all of these...
So, in what way could you be convinced of something You so desperately wanted, needed, and didn't want to let go of? Even if bad for you?
