lol i have the same problem as that guy so i know what you're dealing with here he either wants u to say u miss him or he has a girlfriend and wants you instead of her , and the last option is that he has mixed feelings about u a part of him wants you and the other doesn't (now that's my case) this what i call a battle between the heart and the mind.

Not sure but if he started ignoring you means he is no longer interested. And with snapchat, its social media so basically anyone can really see and check your posts.
