There is a guy I really like and I assume he likes me too, at least that’s what he has always expressed. Generally he has been very nice to me in person and it’s super talkative. But on social media, he always ignores me. For example, last week it was his bday and I congratulate him on fb. Then I noticed he replied to EVERYONE, his family, his friends, his girl friends... except me. Why would a guy do this?
