you are so right Whatfg... what was once your partner....turns a total about face, though in my case I saw how selfish my x had become...
I guess I got fortunate that she did not try and use cannabis against me,but deep down she knew that I could rebuttal.... any stance on drugs that she could possibly take, and do it with authority...
For me with 36 years in at that point ...never really saw it coming...usually by that many years under the bridge...you feel that its not going to ever happen to you....but she was thinking differently i'd say now...
As far as your bro goes...he needs to take that bull by the horns,since two can play that game.
Even if she was never a toker,he needs to paint her in that box...and stick to it wholly and not for even one second admit she did not smoke pot.
It will be his word against hers with a slight twist since (if) he had his MMAR or MMPR etc he was completely legal in what he was doing,however if she does not have legal paperwork to back her up she will be looked at as a person who does cannabis (illegally prior to the current legislation ) and is willing to lie about it.
So when it comes to her testimony he will already have a small leg up.
Plus if he words his side correctly he will not need to involve lawyers,but will easily win over the judge,since judges already know, what most people are all about and they also know she will have zero conscience about lying to the court.
In my case I did not retain any lawyer and still managed to get all of the asset's we had together, changed into my name, the only thing she got was her pension and she knew fully I could go after it as well .... if I choose to.
Mostly because I choose to give up a 6 figure a year job to stay home with all three of my girls back in 1990's,,,, when they were born and bring them up as fully adjusted humans ..... making healthy in the body and mind adults of today...
fortunately they had also, grown up and moved out of the house and all graduated from university by the time she lost her mind.
Deep down I believe that it was the passing of her mother, that started this ball rolling,since she spent 6 months in the hospital with her and I would not doubt, she did everything she could to drive that final wedge into the crack, so her daughter would rethink her whole life..
Her mother did her utmost all thru our marriage to create doubt and turmoil but when I was around she had to shut her mouth, since I would always make her look foolish with my logic.
Tell your Brother,I'm thinking of him and hope things work out to the point that she is not purposely trying to fuck him over and they can at least remain friendly enough to not mess up the kids....THIS IS #1 in importance
sorry for the long post
