Here are some clips from the HULK VS. THOR toon (which I greatly liked. Loved how they presented Asgard and Thor in this and the Enchantress).

Amora is... She's hormonal let's say.

She has this insane lust/love for Thor, but she's not particularly mature about it, or about allowing Thor to come around to seeing her as a potential match. She would rather force it. It's unhealthy. She's that type of person that thinks she can control other people. There is always some kind of conflict in herself. She can be really wrathful against Thor for spurning her but... She doesn't really want to see him dead. She just wants to have him all to herself. She's pure selfishness, and that makes her an easy pawn for others, especially Loki over the years. Now again... She's also a bit unhinged at times, as you can imagine given her rubberbanding between "I love you Thor. Don't leave me" and "I will make you pay for spurning me Odinson!" As for how Thor feels all about this... I don't really know. I think it's obvious that there is a purely physical attraction to Amora, but he's a true and noble prince. He sees her flaws and how she falls victim to her own vanity, lust and capricious emotions. Maybe it's something like, Amora is who he would have ended up with had he not learned the lessons of humility that Odin made him learn by turning him into Don Blake. I don't know... That's my thoughts. I think he might feel some kind of kinship with the Enchantress, or empathy, but she just gives into her dark side too much.
Like I said... Why are the crazy ones so attractive?
