Their love is pure rather than forced by physical, desire, lust or money grabbing.?

Question

Their love is pure rather than forced by physical, desire, lust or money grabbing.

i don't know how to write this in a easier way for someone like me to understand.

'Their love is pure rather than forced' this bit is alright but i don't know how to change 'by physical, desire, lust or money grabbing.'

please help me.

Answer 1

They don't love because of physical reasons (such as the other person being hot) or because or desire, lust or greed - but rather their love is pure.

Answer 2

Their love is pure and transcended lust, greed and money.
