Yeah this whole money thing is a bearpit isn't it? Because it really gets to the whole roots of what your personal aspirations are, how you work together as a couple, what you value in life.
To me it sounds like you have (lucky you) a belief in a true romantic partnership where both parties share resources totally. And perhaps your partner likes that in theory, but when it comes to the practicalities, like him not having as much money for going out, it doesn't seem such a good idea?
That's kind of difficult and I can see how it might hurt your feelings. The pragmatic solution is probably to go down the joint account + pocket money route, but I guess then you end up in arguments about how much pocket money each partner gets per month....
Sorry...this is turning into a stream of consciousness. How about...you get less pocket money than your partner IF he spends some of the difference on taking you out for nice romantic nights out/weekends away or some joint hobby/interest you can both do?
In any event, you definitely need to have a detailed and serious discussion about it. It can be fun, making budgets and plans for what you want to do as a family/couple, so it doesn't have to be a row, but unless you get down to the nitty gritty of what both of you want to contribute to the relationship and take out then it's going to keep coming back round and annoying you, I think
