according to the readme
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This keeps the NPCs from fighting each other or causing each other to leave
the group. In addition, NPCs won't leave if your reputation is too high or
low. [ You must install the first Romance component (Bug Fixes) before
installing this component. ]
***
* Notes on the Romance and Happy components:
* We try to be as mod-friendly as possible by doing patching up existing
* game scripts. Sometimes that may not be possible (e.g., if your scripts
* are too different from the norm because you have installed other mods
* or nonstandard fixes), in which case we will replace your scripts on
* an as-needed basis with Sabre's original, known-to-work Happy/Romance
* scripts. If you're having trouble with a romance or one of the four
* primary romance targets (Aerie, Anomen, Jaheira, or Viconia), try
* uninstalling and Romance/Happy components, reloading a slightly earlier
* saved game and doing it again. As much as we would like it to be
* otherwise, these four characters are such an integral portion of the
* game that it can be very difficult for independent mods to modify
* them without messing each other up.

I suggest remaking a game if it is too hard
I usually cheat my way to my current point and then continue,
