I think there is a huge amount of generalizing in your post OP
I guess I would class as one of those parents but without you seeing behind closed doors you could never understand
Did I merrily swing my way out of my marriage without a Care for my children ? No
But...was there abuse or adultery ...also no
I tried for ten years gave everything I had, and that plodding you mentioned ...years of it
The reality is not a safe staid unexciting life...its far more toxic.
I was modelling to my DC to settle...for no-one to be particularly happy, for them to see no emotion and no discussion. That the extent of a happy marriage was parents who didn't hate each other but could barely be bothered to look at each other, to have any conversation beyond whether we needed milk
They also saw a father who whilst a good man simply came in and sat in front of the tv, with a mother who ran the house and kept our heads above water. The atmosphere was oppressive, awful. There was no screaming or shouting, we didn't argue or bicker we just stopped caring. We managed to take it sometimes but frankly my DC are not stupid and it became exactly that...fake
I started to realise this couldn't continue and I remember every day for a month at least sobbing convulsively in my car on my way home from work at the thought that I was that vile to consider talking to Exdh about it. That I could even consider breaking my children's home
Because that was the only time I could risk being emotional that they couldn't see
Meals were eaten in silence because no-one had anything to say
This was after trying and talking and trying
I stopped sleeping in terror at the thought if ruining their lives
I begged my Exdh to try...he always agreed and was a kind man...but nothing...literally nothing
The boys were listless and quiet ...it was like being in a mausoleum
I remember going for a run one night stopping and sitting in a pavement shaking and sobbing at the life they had
We lived in a three bed semi in a nice area and it all appeared to be perfect
But it wasn't
So after ten years, three years of doing everything to make a happy home again once it had gone bad and months of tearing myself apart I talked to EXDH who agreed having gone through the same
Easy? No ...no it's not easy. I haven't even touched in the guilt , the fear, the transition
But with all that....it would have been so so much worse to continue. To have brought my children up with the belief that that's what love looked like, that possibly the most important relationship of your life other than your children should be so oppressive and in loving. Far worse
I understand you have your views but please think...i didn't end my marriage for fun or kicks or for somethi g better I did it for my children (not that in the rest of my breathu g days will they ever hear that or ever have)
I have a new DP (known for years well trusted and vetted before being within ten miles of my dc) and you know what they hear now in their home? Laughter...games, argued fun debates about dinosaurs. The biggest issue we have in relationships in our house is who caught the last butterfly in the elephant game or which train to take to bed
We a rent perfect but this is what they know love is
That's worth it for them to feel and see happiness...not just existence
