goosebrry,
Well, as a guy, I felt that if I'm dating with this girl (as bgf), of course when we went out for meals, I will pay for it. Unless if she insists on paying, or perhaps she wants to buy me a meal or what, I appreciate as well. For trips wise, unless I have the 'additional cash', otherwise I think its fine for us to pay our own share on the air tix (especially). Hotels wise of course I don't mind paying, and maybe transport expenses/meals during the trip. But shopping wise, I think still basically she have to pay her own.
If planning to get married, I think its good to talk about such before marriage. Maybe like what the others did, to contribute into a joint account, and used it for payment of utilities etc. Like for myself and my ex wife, we have a joint account in which monthly we chip in some cash (Since I earn more, hence I contribute more, maybe like 70-30 or 60-40?) We used this particular account for air tix (if travelling, but hotel expenses still comes out from my own pocket money), households bills etc. But well, even when we went shopping for grocery, I do pay from my own pocket money as well, despite we said to use the joint account.
atthexroad,
I felt your bf is really trying to take advantage of you. You really need to consider carefully, especially in the long term run. But base on what you describe, to be honest, I think few years down the road, he'll still be acting this way.
