DE income tax for MD residents (taxable, credit, money, cost)

I have been at it for the last couple of days and I am totally confused on why my DE state taxes are so frikin high. Especially since I live in MD.

Now my wife works in DE but is a MD resident. I understand that SHE has to file taxes in DE as well as MD as stupid as that sounds but I see it in the rules. Well, SHE"LL at least get somewhat of a credit on her MD taxes for those paid in DE but it is still an extra pain. And she really loves having both DE and MD taxes taken out of her check which together is more then the federal, and she still owes to the 2 states.

Now we are filing jointly. So it seems the state of DE wants MY money as well and I don't even work there. When I add our incomes together and follow all guides on H&R Block, Turbotax, and taxaid the DE taxes to be paid keep increasing with every bit of income I add of mine. I add MY MD W2 and our DE taxes go up. I add my self employed income and our DE taxes go up, MY misc income and they go up. Even MY investment capital gains cause the DE taxes to go up.

Is this screwy or what? I don't live or work there and now we have to cut a check to the state of DE for taxes which are double what they'd be if my wife filed single. She works there, I don't. Why does my income get to go to our neighbor. It's bad enough paying the ridicules taxes here in MD but to pay even more to a state we don't even live in?

I guess so called low cost states have to get the revenue somehow, even if they have to take it from their neighbors.

And just to humor me even more now that I have them filled out. Our DE taxable income comes out higher then MD's taxable income.
This is doing everything right according to the program.
It ask's for any DE income which is separate but automatically inputs AND TAXES all other income as well.
I am beginning to hate the state of DE.
