Nah, it's not shame on me.
In my past I've run away and told my DH I'm out of there because I wasn't coping. Last year I contemplated suicide, it wasn't manipulation or any reaction to my DH. I couldn't cope.
I'm lucky my DH is a better person that most of the posters on here. He recognized I was in trouble, didn't see it as a reflection on him and didn't think I was dangerous and violent or nasty because of my meltdown.
Since then I've got help. I've learnt to cope, adjusted my life, can see the signs, appreciate that there are triggers that tap into my past which means that to anyone else I'm overreacting but to me it was overwhelming. DH understands my problems a little more as I now do thanks to the help I received. I didn't make the links before the help I've had.
Is her DH a bad man?
Is he a good man who's lost his way?
If he's a good man, is he worth the trouble of working through this?
If he is, is he prepared to try to change as it one person can't try enough for two.
Many of us have struggled and had crisis and needed some extra help with doctors or counselling and despite it all, have good marriages.
Only the OP can make that call. None of us know so assuming the worst, pushing that view and trying to put down anyone who disagrees may be damaging to the OP.
