I can probably fix that...
What if your LI ends up betraying you a la Jacob Taylor?
is the main motive now Jacob face almost always the tube in my ME2 runs. no matter if I didn't romance him. Is one of those thing I can't really forgive to a man (or woman).
betray someone, and having a child with this other person, without breaking before the realtionship you already have is for me a very big form of immaturity and cowardice. expecially having a child. Damn, there are many way to prevent pregancy!!! from pills to condom, to the more effective of all, as Gandhi sayd: abstinence.
And in a future like ME3, I can't think two adult, one a soldiar, the other a scientist don't know how to prevent pregnacy!!!
I can be less angry if something similar happen in the DA setting (less culture in general, and less 100% efficient way to prevent a pregancy, beside being both Gray Wardens, it seem.) and the betray (without pregnancy) I can be ok, but only if is the consequence of determined choices, and not arbitrary. and if arbitrary must be, I'd like the chance to continue the relationship or not. (I don't think I will forgive something like this even in a game, but I had forgiven Anders, so I can change my mind playng)
