I don’t know if I should break up with my boyfriend...

I’ve been in a year long relationship with this guy and at the beginning he was so sweet and always hyping my shit up and I could truly tell he was in love with me. Now he calls me a dumbass and always finds a way to make fun of me and whenever I call him out he says “I’m just playing babe”. He never makes time for me anymore but when I confront him about it he always has an excuse. I am still so in love with him and I still have hope but I don’t know if I’m just forcing myself to say that so I don’t admit that he is walking all over me or if I really have hope he is going to change. He treats me like one of his guy friends and some of you are probably thinking “uh girl drop him” but I’m really not ready for the heartbreak on my part but also I know if I break up with him he will have 0 emotion towards it and I can tell he wouldn’t even care I’m not apart of him anymore. He made me so happy at one point and I just want that guy back. I have talked to him about how I feel but he usually ends up switching it on me and making me feel like I do everything wrong and I’m just being over dramatic but typing this out is making me realize I’m really not. I just need some help and guidance from someone please:(❤️
