Can't stop crying

I think I've cried just about every day this month. I've come to realise that love isn't the positive emotion I always believed it to be. It fucking hurts!! My "friend" doesn't want to commit. He told me plain n simple there's no "spark" for him. I know I should walk away from that situation but I actually love him. Even though it makes me feel like absolute shit when I'm reminded he couldn't care less.
