I mean, grown-ass man dating a sixteen year old, grown-ass man who can't cope with women being stronger than him, or actual stalker. it's so hard to choose just one! (I do like angel and spike as characters, although riley could have been interesting but ultimately kind of wasn't, and i think all three's relationships with buffy are interesting and even fun to watch, but none of them are anything close to healthy. The only real ship is buffy x a bucketload of therapy, girl has some serious issues around relationships)
