Your h was throwing a tantrum yesterday about the dogs and when he saw your son stepping up to the plate to watch them, notice how he opted to go along too? He's mad at the world, but most importantly, he's mad at himself and doesn't understand why he's doing the things he's doing.
I think that's a really important aspect of people in general and perhaps especially with MLC...
When someone is struggling with their own issues... having a good role model...
in this case, your son's responsibility and behaviour being a great role model for your H to step up and meet... it's really important for those who are "lost" or "struggling" in their own direction, path, growth...
We could say that if it weren't for your son, your H would not have been responsible or supportive of you going out and GALing, Wendy...
Or... we could suggest the only reason why your H did get involved in a positive way was to prove that he was a good person...
Let's not take away what he did that was positive... and layer it in some sort of negative light...
Your H is lost... as are most MLCers... and they are seeking role models who possibly aren't as well developed as the MLCer is, themselves... and so they follow those self destructive paths of others... or just have no direction and are franticly drowning in the shallow end of the pool...
And perhaps... if they are surrounded by positive role models, they too will step up and behave in positive ways...
