Trying to win back my ex?

My ex really loves yogurt. Like any kind, brand, flavor, he just loves yogurt. So I always send him text pictures of yogurt whenever I see it. I send send at least one picture of yogurt every few hours to let him know i'm still thinking about him. Do you think this will help me out? Should I send him more suggestive pictures of yogurt? or send them more often? ANy advice would help me out, thanx.
