Should I stay or leave my relationship need help!!

Me and my bf have been together for 4 years now. My freshmen year of college is when we got together. It started out really good for the first 6 months. Then he wanted to spend more time together mind you I was a freshmen, and I was on the cross country team and the track team. Because he wanted to spend more time together I basically slept at his dorm ever single night leaving my roommate alone who I really loved she was super sweet. Anyways he basically wanted me to stop hanging out with my friends as the years went by. I did what he said and now I basically lost all my college friends who I loved so much. Back to my freshmen year he would always get mad when I went off to practice with the cross country team. I didn’t really understand why he got mad at me. I spend literally every waking moment of the day with him that I had to spare. This is why I lost all my friends. Anyways I am conflicted because it is getting to the point where he apparently knows my location now. So I turned off Snapchat location just for him. Let’s see if he notices he probably will. He might also get mad which might be a given. He also kind of has very narcissistic vibes coming off of him now I have noticed ever since he knew where I was. And a little background on how I think he knows where I am at all times is because I am still commuting to college. I was on campus because I got there like an hour early and he happens to show up “on his lunch break” and he kinda said based on the map this is where you were. I don’t think he meant for that to slip out but it did. That really kind of creeped me out a little. I am just so unsure about my relationship now. I need advice on how to get out of this relationship or if you guys think it is worth staying in and figuring things out.
