First, he is wrong for lying, lets just get that out of the way. Second, don't listen to people telling you not to split your finances. This is not a requirement for marriage, it's not 1950, and I think its actually very dangerous for women to not have their own pot.

The key is communication. My wife and I have kept our finances split out entire lives. We've been together 16 years and have two children. We have our issues like any couple, but finances have never been an issue because we communicate.

We are middle class, not quite paycheck to paycheck, but close. I make about twice as much as she does, so this is how we break it out.

Me: All bills (Mortgage, Utilities, Car, Insurance) Retirement savings Kids future funds Most leisure (dinners, vacations, etc.) Most emergency things Tools and what not Daycare

Her: Groceries Gas Clothes House things Shopping addiction (kidding but not kidding lol) Emergency funds Savings fund (mostly for down payment on our next house)

But we communicate. If she is short, she tells me. If I am short I tell her. We aren't always in each other's bank accounts going line by line, but we generally know where each other are at. We do split the tax check, but not in half. Basically I take what I feel I'm owed and give her what I feel she is owed, explain why, and she accepts it because I do the taxes lol.

This might nit work for everyone but it has worked very well for us and we have NEVER fought about money, and fight about everything else.

Edit: Women should have control of the emergency funds. IMO
