It's alarming, isn't it.
When one has a young child, and things seemed to be working out ok, we'd bought a house together, young child, things seemed to be fine, although the sex life had taken a bit of drop...and we were arguing more, but nothing BAD, nothing to divorce over..
My clever Dad.. we used to joke he was like Sherlock Holmes..
We were staying at my parents for Christmas, and on Boxing Day, husband was going to see his parents ''on his own''.
My Dad said to me ''Go with him, love, just go''
I said ''But I want to stay here with you!''
Dad said ''Please go...I think you'll
regret it if you don't''
I stayed with my parents - but.... Husband wasn't at his parents when I phoned.
Dad had taken a note of the vehicle husband had, and there should have bene no more than 18 miles on the clock.
There was over 280.
He'd been up to see the OW.
Dad said ''he's been acting suspiciously..your husband never reads books here normally, but he's been clutching that book a workmate gave him like a precious object all day...she gave it to him.
Dad was spot on.
So sorry you had to go through it, too.
{And OP of course} ...such a hard time of year as well for them to leave, especially with children.
Happily my ex 's second marriage failed {schadenfreude} - thanks to OW's children {who bless them were kind to our son}...I hear one of her son's names on Radio 4 occasionally in credits, and am always thankful that he was nice to a hurting younger child, as he too was hurt by his mother bringing in a new man.
