I don’t think i love my boyfriend, and i don’t know if i should break up with him

Let me try to get you guys a better understanding of him as a person before i bring up all the pros and cons. Hes a bit overweight, doesnt have a job at 22 because he goes to university, pretty much plays games on his computer all day, doesnt really have any future plans or goals.
However he is a really good person, he has never yelled at me or cheated on me, he’s very understanding and forgiving, he does a lot for me, buys me things etc.

We started dating over a year ago. At the beginning of the relationship he lied about his age, telling me that he was one year younger than he actually is. Doesn’t seem like a big deal but i was underage and he’s four years older than me.
After a couple weeks/ a month of talking he kept pressuring me to be intimate with him. I don’t know why i just looked over all the red flags and got into a relationship with him. The first couple months weren’t bad, i liked being around him. But it all changed very fast, ive told him from the beginning that his looks are important to me, i wanted him to be in shape and look after himself like i do, he would always agree with me and tell me he will start doing better but he never took action.
Overtime i started noticing more and more things i didn’t like about him, it seemed to me that he wasn’t that smart and i felt that at times i was more intelligent than him ( but that is probably my ego speaking) i realise that thinking of him as someone below me isn’t the best thing i could do, I just cant change the picture i have formed of him in my mind.
We’re now dating for over a year but i dont feel like he’s my partner, i cant see a future with him since all he does is stay in his comfort zone, i don’t feel physically attracted to him? i don’t want to be affectionate with him. Most of the time i don’t even think about him. But im scared im gonna lose a great relationship just because i didn’t give him enough time to change and work on himself, the past month hes been going to the gym and i guess trying to get better, but ive lost all my hope.
What should i do??😭
