I feel like he’s getting more possessive?

Recently my boyfriend has been more possessive..I was dressing up recently and he was wondering if it was for someone else. I stayed in a hotel for my birthday and he thinks I was doing something shady. He gives me hickeys when I don’t want them. Even my coworkers notice and it’s embarrassing. He has a really good side but I don’t like to be controlled. Should I break up or talk to him about it?
