@paradiseplanet27 Well, I'm not sure it'd be a good idea to make all gifts react positively. Something is effecting it and making them turn it down, I just don't know what. I know their current mood has something to do with it.
Like, I know if I do a high-level romance interaction too early, it will end up with an "Awkward conversation" moodlet. After that, all romance interactions will fail, even the low-level ones. I have to get rid of the "awkward" thing before I can attempt any further romance options.
It could be something like that. Some moodlet on the target sim is causing it to fail, like maybe the sim is sad, awkward, tense, cold, hot, etc.
