The taking of the money I'm a bit 'meh' over. 20 of petrol for ten school runs plus any family running about for two weeks (not a week as some have misread) is not a lot.
Initially the op said she thought 70 was missing. He admitted taking 50 - at which point she said it was more like 100. Everyone has now jumped on that figure, despite it only going up partway through the thread, even though the op had counted it at the beginning and deduced that it was 70.
70 is closer to 50 than 100. The opinions couldn't be sure if she'd taken more than she thought either, so it's not unreasonable to assume he may have done the same.
By the op's own admission he had taken on the role of sahp - doing the school run, housework etc.
I can't help but think that if ANY sahm posted on here that they did all the school runs and housework for 10 a week petrol money to take the kids to school, and when they dipped in the change pot in the house their dp called them a thief we'd all be screaming financial abuse in the other direction, talking about how the sahp role is an equal contribution and all money should be family money. Seen it a thousand times.
The op invited this person to join her family, and live with them as a family. He took on the role of sahp, doing the tasks that millions of sahps do, doing what I. DO every day - but apparently when I do it it's a valuable contribution that should entitle me to share family money, yet when a man does it he's a 'cocklodger'?!
Does that mean that all sahps are cocklodgers and thieves if they touch their dps change jar?
As for the accusations of cheating, the gas lighting and the phone checking - yes those things would earn him the door in my house.
But taking change from a jar? That wouldn't be stealing to me, because if I had a partner and moved them in it would be with everything shared. He may not have contributed financially, but then neither do the vast majority of sahp - and I doubt anyone shouting cocklodger at this man would dream of saying the same to a sahp. He may not be their parents, but that doesn't change the fact that he was doing that role.
