Y'all I need some advices

Well I've seen that people these days are too romance and sex oriented (idk if we write it like that but you get the point). Well me being an asexual +aromantic (in other words I can't be romantically attracted to people) I'm lost, like really y'all I don't even know how to reject my imaginary weeb friend so how do you expect me to do it in real life bruh. So give me some advices I need your help ༎‿༎
Ps: I broke my mother when I told her that I never wanted to get married lmao
