My bf wants to go on a break, what do I do?

My bf and I have been arguing a lot lately, and now he wants to take a break. I'm really scared because I got way too dependent on him—it's weird not being on the phone with him every night. He says I need to work on myself, which I get, since I've been super emotional recently. But he's also been provoking me, making it hard to have a calm conversation. Since he just started college, he has a lot going on, and I feel like I'm just adding to his stress and causing problems whenever we talk. It’s confusing cause when we were together last Friday everything was good and now I’m scared I messed everything up between us. What can I do to better myself for our relationship to work out long term
