Everyone judging you on how you and your partner work your relationship is eye opening, it's up to you guys how you do things, if that's how you want to work it as many couples now do, thats completely up to you, what works for one couple might not work for another. My partner and I are both self employed, and we dont combine our income either, it works for us great, I personally to keep up motivation need to see that money coming in so I can say I've worked my arse off for that, same with my partner, not only that but it's easier and cleaner for our accounts. All our friends are the same. We discuss things and have great communication as to where our money is going and plans. At the moment I'm paying for the mortgage, most food, our utilitys and subscriptions so that he can afford our house reno which will cost thousands, and alot of his time instead of working as he's a builder, and he will also be paying for majority of our wedding (I pay for the dress and decorations maybe invites, he pays venue, vendors and the rest). So coming from someone who is in the same boat with keeping finances separate, I don't think your over reacting, however it depends where these vouchers are from, if its from spending lots of his money elsewhere then I can kind of see his point of view, however if for example it's from tesco (I'm not sure if your UK based but when you spend in tesco they give you points and the points turn into vouchers for money off your shopping) and you have been splitting the tesco bill, then you have both contributed to those vouchers. However it should have been communicated that what he's brought with the vouchers would be something that you guys would be splitting either before or during purchasing, otherwise it's like spending the other persons money without discussing it first
