Is he actually done or is this a control thing?

I’ve had this situationship for 2 years basically. He’s INSANELY toxic and everyone on here has been telling me this for a few months. But I’ve struggled leaving him. So I thought I finally had my chance today when HE ended it with me. Everything was totally fine all day. HE was double texting ME and telling me about his day and stuff. I was telling him about how my new coworkers were really touchy and I didn’t know how to deal with that, basically. Then all of a sudden he got weird and was like “idk do whatever you want. Stop asking me questions” basically. I was really confused. Then basically starts telling me that he’s done because “it’s toxic”, how he doesn’t trust my opinion of people, doesn’t trust that I’m not doing something, how he doesn’t like that I don’t tell him enough details about who all my friends are. After the initial feeling, I felt relieved. But then when I was talking to my family about it, I realized that it sounds like he’s upset because he’s losing control and just trying to regain it. He “breaks up with me” every so often but I thought he would really be done this time. But maybe he’s just trying to get control over me since he can’t get it from working together like he used to. He’s telling me to stay single and all this stuff too. 😵‍💫
