Re: Is this insane or is it me?
Suppose it depends on what you want.
do you want to support him freeloading? do you think you should be entitled to get some freeloading going on?
Personally, after several tough relationships; one with a spouse that spent everything, and loaded up the relationship and house with as much debt as her banking employer would let her.
Separate accounts. A separate account for bills. solid budget, with reasonable labor allowances&expectations and clear division of routine responsibilities&expectations. It will help with your relationship finances such as investing and property to have such things sorted in advance. You'll also find out who is supposed to cook - is it you all the time? what about the washing and vacuuming? Any take out in lieu of cooking must come from that persons own savings, and be for the family, if it's their responsibility night - keep flexibility for hobby nights or visiting others.
If that sounds too hard, or harsh then do you really think a _lifetime_ commitment is going to be easier?
And discuss what is going to happen in case of babies (including unexpected ones!), job loss, major illness.
Far better to have expectations of chores and bills worked out way in advance. And also I'd keep away from 1 pays bills and other does the savings and holidays - such things can go badly very very fast if the relationship has problems, or financial problem occurs (eg identity theft or investment losses).
and just because he (or you) gets more is no reason for them to pay more for basics.
