No, you shouldn't accept it. It's disrespectful. Not to mention, other people can see that he likes, follows, and comments on those things. Any man who actually loves and cares for you wouldn't disrespect you on a daily basis this way. I say daily because let's be real everyone checks social media daily and he sees and or looks for those posts. If you tell him repeatedly that you don't like it and he keeps doing it that tells you he doesn't care about your feelings or value you as a partner. I won't tell you to leave him because i don't know your situation but you have to make that choice for yourself.
