This is the objective answer.
You are forced to either let Morrigan cuckquean you or either you or Alistair die.
If you are not a human and instead are a dwarf/elf female and romancing Alistair you have to be his mstress since he has to marry a human woman.
Alistair in of hiself is a good dude, just the circumstances really fuck the female MC over.
Bioware really shat on femcels.
