what would you think

How would you feel if the guy you were dating for 2 years completely ignored you on social media? Everytime you share or post something he never comments on it or likes it. It's not because he doesn't see it, because he goes on there constantly and is always on other people's posts. He likes other people's posts and shares other people's things, but even if you tag him in a pic, 98 percent of the time he won't even acknowledge it. Never has posted anything about the 2 of you unless asked to, or anything. But before you started dating was liking all sorts of other girls pictures and commenting how beautiful they were. SOOO, how would you feel? (Yes I know social media isn't a big deal blah blah blah, but how would you genuinely feel. please don't be mean)
