Wrong or not?

My boyfriend recently made a whole bunch of social media accounts after years of not having them. he's given me all his passwords and told me i could get on whenever and so far the only thing i've really had a problem with was instagram. 
is it wrong i get insecure and jealous that he spends so much effort and time looking for, following, and liking half naked girls (pictures) but barely spends time with me or tells me that i'm sexy/beautiful? it's gotten to the point that he's been finding young women in our area and liking their pictures until they follow back. He's been attached to his phone and his games rather than wanting to spend any time with me outside of the bedroom.
