Please don’t take advice from strangers off the Internet. I wasn’t all that excited about my wedding- more like i was terrified- and neither am i sure what anyone means when they say ‘chemistry’ but i spent my entire engagement asking married people if how foolish it was that i logically knew he was the One but i didnt feel what i imagined to be chemistry. I dont recommend you do the same but somehow I was blessed with the most incredible husband who is perfect for me in every way thank God, bli ayin hara(!!!). if I would’ve explained my fears on an anonymous forum it’s not a question that I would have been recommended to break it off chas veshalom.
My advice? Ask someone you actually trust who knows you. This is the single most crucial decision of your life and you don’t want to make the wrong choice because some well-meaning nobodies on a blog told you so.
