I (20F) cant figure out how I feel about my boyfriend (22M).

Me and my boyfriend have been dating for almost two years. We did have a huge bump in the road during the summer, and I told him he had 5 months to fix himself or else we wouldn’t be together. That deadline is December. He has been making an effort to be a better boyfriend, as well as taking care of himself which he previously didn’t do, such as not brushing his teeth, working out, showering, etc. I stuck beside him until I got tired of it because I had lost all of my independence and sense of self because it was constantly him him him. He started going to therapy though, taking care of all of his hygiene, etc. BUT, he wants to hang out, a lot. Although for some it may not be considered a lot, it is for me. I have a very busy schedule and actually have to tell people “please ask me to hangout on a specific date 1-2 weeks ahead of time so I can see my availability. He is no exception, and if I’ve made plans with someone, I tell him i’m not dropping them, especially if it’s a friend. It’s disrespectful to my friendship. He doesn’t seem to understand that I am constantly busy with balancing university, working out, having a job, and doing my homework, while also having a curfew (yes I have a curfew due to certain health circumstances). No, he is not in school, and with his job he only works two days out of the week and does whatever. I am happy with him, but when I say that I mean directly with him, when we hangout. Outside of that, I feel weird. When we aren’t talking to each other, or in person, I get this weird vibe in my stomach that says he won’t be able to keep up with my life style and is holding me back. I do love him, yes, but I can’t figure out this underlying feeling. I don’t know if it’s attachment, if it’s me being anxious, or something else. It’s unbelievably frustrating for me, and is taking a toll on me due to the stress. I can’t talk to anyone else about this either because of the fights we had over the summer ruined his image with everyone I am close to. They don’t even know we continued to date. I’m scared to talk to him about this because even I don’t know what to say.
Is this normal or not?
