I broke up with my bf and I don’t know how to handle it

About three weeks ago I (24F) broke up with my bf (25M) because of his short temper. It reminds me so much of my dad and I realized that I don’t want a marriage like my parents. My ex gets defensive over everything and I feel like I’ve only scratched the surface of his feelings. He doesn’t know how to talk about his own feelings and he’s uncomfortable around mine. I suggested therapy and he was open to it when I first brought it up but now he’s not sure it’s something he can go through with. He doesn’t know how to comfort me how I want and need to be comforted. He knows how to help but he just doesn’t. I love him so so much. He’s still yet to apologize for the events that led up to the breakup. I think he’s just done with me and it’s breaks my heart bc I don’t feel done with him. All I want is to be in his arms which is stupid bc my friends have been more of an emotional comfort to me the past three weeks than he was in our nearly two year relationship. I just wish things were different. I want him to be different.
