Boyfriend follows ex on all social media and then I see this...

Okay...so I need to know if I'm over exaggerating or not. My boyfriend still follows his ex girlfriend on all social media and still looks her up..we have been together for 2 years now and we live together...I've asked him to unfollow her on all social media and he told me no...then I saw this on his Google account..after he looked at her Twitter. I'm having mixed feelings about it..what fo you ladies think???

UPDATE!:

So I asked him about it, he told me that he didnt visit her page on Twitter. he said that when he went to pull twitter up it was already there from a previous search. then he said that he looked up on Google why I've been so distant but saw those articles on the side so he read them.....I left it alone....fast forward to yesterday I see this

when I asked about it. he said that he still has anger from when he was in college and he thinks about 2 of his friends who are not friends with him often and wanted to know why.......IDK!! I want to believe it so bad....but I just dont know
