I think Kore is right on. I do not believe he meant love as in marriage and children and all that crap. More like how a man regards a favorite pet. Unless you are really sick you don't want to damage your property or make them want to run away. You certainly don't want to over do it, but a little affection, a kind word, praise for a job well done, a simple caress, helps keep your pet attentive and wanting to please you.
Ksst, what put you over the edge? You sound like you are in a healthy (?) relationship where you can give some feedback to your master.
