Feel stuck in my engagement

So im 24M, and about a year or so a go i got engaged (through a marriage broker in the community) to a girl who was 18 at the time. Before the engagement, our families met each other. After we met, i told my mother i wasnt attracted to her and the age difference was too much for me, but somehow she convinced me that the family is really nice, the girl is mature and once you talk to her and get to know her everything will be fine. So we got engaged and we got i along pretty well. We are quite close at the moment, we regularly meet each other and talk every night (she insists on it). However i always have this feeling in the back of my mind that im not attracted to her, even personality wise we are complete opposites. Her interests and hobbies are shopping, attending events(mehndi, dholki of her relative/ friends) and meeting people(cousins friends etc.), while i am more introverted and inclined towards sports, fitness, gaming, memes etc. i wont go into much detail, but we literally dont have any common interests. I constantly have thoughts of breaking the engagement but i feel that she is so strongly attached with me and im worried how it might affect her. Shes constantly messaging me, asking me if im fine, and if i dont express my love before saying her goodnight she doesnt sleep well. A few months ago i let her know my feelings (things mentioned above) and she cried so hard, I couldn’t see her like that and lied to her that i was stressed because of my work which is why i said things like that. I really love her and want her to be happy but i dont want to be one of those people who feel stuck in marriage. We are about to get married in 4 months, everything has been finalized, dresses bought, venues paid for and a lot of money has been spent from both sides in exchange of gifts etc. I dont know what to do , i feel stuck…
