So, you're saying that before your husband MADE you hand the wallet with the £200 in, he thought about ways of keeping the £200 (of someone else's money!) ... Even though he is an ex copper. (You said this on a previous post on here that he's an ex copper.) An ex copper would KNOW you don't just keep a wallet full of money that you have found! In fact, the vast majority of people know this!
You asked on AIBU, so you KNOW (deep down) on every level that you're in the wrong. Why are you doubling down? EVERYONE on here (almost) is telling you you're being unreasonable, to even think about keeping the money.
You started off by saying your husband MADE you hand it in, and then said later in the thread that he tried to think of some ways to keep it. What ways? What was in this brainstorm he had, what ideas did he have to 'keep the cash' and then go on to decide he is making you hand it in. And all this when he wasn't even with you?
I'm done on this thread now. I can't keep up with you.
YABU definitely though. And you know it. That's why you're so defensive. And you only did the 'right thing' because your husband made you.
94% of around 750 posters so far are saying you are wrong and YABU. Accept this and move on, and stop making excuses.
As I said, I'm done now.
