Once you have love as a motivator in a story, your character is free to do anything. Once you say the character is in love, he can do the craziest thing that nobody would do who’s not in love. Once you’re in love, you have that excuse to go and do whatever you want.
“Love is tested in so many ways. How do I articulate this? Two people are together. There are stakes, strife, struggles, all these things that make us fall for someone, love someone even more, leave someone.” - Ian somerhalder
