i dont think you're too young to be thinking about marriage, it seems like you are very mature for your age, and not like most boys who seem to be all over the place.
with regards to seeking a marriage partner, is there anyone who could talk with that could help you find a wife? maybe an older figure, like your local imaan.
maybe get in touch with some practicing brothers or sisters who know of people wanting to get married.
Asalam to whoever is reading this. Im a practising muslim alhumdulilah and really want to get to know somebody who may be interested in marraige.
I dont know if this would be better in the freindship section but i want a sister i can talk to for a while and then if allah wills we can possibly get married? Im 18 and i am from UK. Please contact me :D
