To be or not to be?

Basically I'm writing this for some advice. I've been with my partner for over a year now and I love him... I'm just not in love with him. He's done nothing wrong but recently I feel like we've lost that spark. Our lives are going in two very different directions and I'm not sure what to do. Should I wait it out and give it another shot or would it be kinder to end it now? Advice please?
