Help🤔☹️

I've always had commitment issues, to start out with. Can't choose a favorite color, food, restaurant, subject in school, college, what I want to be when I'm in college, and of course, boys. Before T, my longest relationship was 2 months, I've been with T for a year and 3 months. I love him, we are inseparable, but that's starting to suffocate me. I'm starting to feel that breathless, need air and space feeling that I used to feel. But, if I break up with him, I would not get him back because he would be so hurt. I'm scared to give up when I don't know it this is what I want or if it's just the commitment issues rearing up again. Please give me advice. I could really use it 😕
