This young creature was staying at the boarding-house where I happened to have my lodging; and when I was pulled down she took upon herself to nurse me. From that she got to have a foolish liking for me. Heaven knows why, for I didn't encourage any such thing. But, being together in the same house, and her feelings warm, there arose a terrible scandal, which did me no harm, but was of course ruin to her. (12.23)
Love can ruin a girl's reputation, so watch out. Henchard isn't very delicate in his description of how Lucetta fell in love with him; he calls it a "foolish liking" that he didn't "encourage" at all.

Nobody would have conceived from his outward demeanour that there was no amatory fire or pulse of romance acting as stimulant to the bustle going on in his gaunt, great house; nothing but three large resolves: one to make amends to his neglected Susan, another to provide a comfortable home for Elizabeth-Jane under his paternal eye; and a third to castigate himself with the thorns which these restitutory acts brought in their train. (13.8)
Henchard isn't in love with Susan; he's only marrying her because he feels obligated to.

But Donald Farfrae admired her, too; and altogether the time was an exciting one; sex had never before asserted itself in her so strongly, for in former days she had perhaps been too impersonally human to be distinctively feminine. (15.5)
Once Elizabeth-Jane starts wearing fancier clothes, all the young men of Casterbridge (including Farfrae) start to admire her.
