Romanced Alistair in DA:O: he either dumps you, dies, you die, or he gets raped by Morrigan
Romanced Anders in DA2: he goes crazy, bombs a church, kills a bunch of innocents and starts a war...***!
Romanced Thane or Jacob in ME3? One dies, one takes Usher's songs as a lifestyle, female Shepard is left with zero male romance options.
Romanced Solas in DA:I: >:'(
Romanced Theron: ??? BioWare don't do this to us again! If you must have another tragic romance it's time the female LI's get hit with the angst hammer!
