"Love is a decision" is a tenet of Michele W-D's work (and many others'). Feelings come and go. Mature folks make a decision to love. That doesn't mean that they can control their feelings, but they control their actions so as to promote loving feelings and they control their thoughts, which are the source of their feelings.
H gave the right answer. Don't give him grief for it!
If you really think that your feelings just happen, and you don't choose to love, then I'll just have to quote a line from an old Adrienne Rich poem: "Only she who says she did not choose, is the loser in the end."
