Lust is nothing but merely physical attraction without Love! As soon as the cloud of love envelopes your being, the same lust transcends into love!
You can live happily with a person whom you respect but do not love but its really tough living with a person whom you love but hold no respect for. At this point in time, Kripa is both in love with Angad and respect him (she does, inspite of what she shows outwardly) and she only respect and admires Prithvi but does not love him! When Angad lets Kripa down, her respect for him will go and with that the love will also fade away, albeit slowly but surely!
You cannot remain in love with a person whom you do not respect but there is a lot of chance that you might end up falling in love with a person whom you respect.
Kripa is truly, madly and deeply in love with Angad and she is full aware of her feelings, hence if she consummates her relationship, it will be ''An Act of Love'' but Angad is not sure what he feels for Kripa, he is attracted to her, he misses her, he enjoys her company, he cannot see her with anyone else, but does all that culminate in Love? I for one, do not think so. Hence, if Angad connsummates this relationship based on his relationship with Kripa, it will be an ''ct of Lust'' or to put it less controversially, ''An Act of Physical Attraction''.
So, Love and Lust are completely relative terms, they differ from person to person, from individual to individual!
Kripa is definitely in love with Angad, the person, not his image, but Angad is in love with the ''Kripa - whom he could not have'' For him, Kripa is the forbidden fruit, which he wants to acquire at any given cost! I think the thrill of stealing her from Prithvi gave him a high! But this is not saying that he is a bad person or something, Angad is just confused. For a person who has not seen the existence of love in his life, he wouldn't know the deeper meaning of this emotion till love goes away from his life!
Only when Kripa leaves Angad, will he understand that he has truly loved someone and lost that person.
Cheers,

PS: That way, Prithvi's love is of the highest order! Will post something on it later!
