He’s barely contacted me in 2 weeks

I have been dating this guy. We hung out almost every weekend and had sex a few times before winter break. I thought he really liked me but over break he rarely texted me or he would go silent after a few replies. I also noticed that he updated his tinder profile. I was upset at first but I thought were not official and are not going to see each other for awhile anyway. After break I snap chatted him and we talked almost everyday for a week and then he came over and we had sex. I texted him a few days later but he stopped after a few replies. I didn’t hear from him for another week until he sent me a Snapchat of a dog at the gym. A few days later he sent me a picture of his roommate’s cat. I was upset and deleted him from all my social media but I don’t think he noticed. I started wondering if he was upset because when I didn’t have a condom I had said “I must’ve run out.” I asked him what he was doing one night and he said he was watching a movie with his friends. Again he stopped after a few replies. I added him back on my social media and sent him a pic of a coffin I found on Craigslist with the caption this is how I want to be buried or something like that. He replied that Craigslist is a scary place. He didn’t say anything about how he did t contact me for almost 3 weeks. My question is should I move on from him? I’m not even sure if he’s ghosting me or not. Is he playing with me or did I do something wrong? I thought he liked me but I don’t know anymore.
