Do you think some 'coincidences' happen on purpose?

Today, and a few days ago, many so-called coincidences have been happening. The whole thing is starting to confuse me, it’s about a guy. What should I do?

Everything starts to add up, then another coincidence pops up, and I’m even more confused. What does it mean when he tries to distract himself when I’m around, but keeps staring, and flirting with other girls in front of me?
(These are not the coincidences I’m talking about.)
