Am I overreacting?

So my boyfriend continues to like other girls photos, who are 100x better looking than me and skinner than me, even after telling him I don’t like it and it makes me upset. He’s also always on his phone when we’re together but when we aren’t I get really slow replies even though he’s at home doing nothing, he ignores my calls etc. Am I overreacting and overthinking or am I right in being upset
