No friend of mine will attend my marriage in near future

When o think about it,I can’t find a single person to rely on who would attend my marriage whenever it is The same happened with my brother I think we are quite the same , we are introverts don’t have social circle ,only colleagues etc Not sure how it turned out like this Pursuit of career and shaping of us as a person by parents might have to do with this I am not sure how girls feel about not having a single friend attend the wedding of their future husband
