Its not hard to keep yourself chaste. Plenty of people manage it before marriage. And no you don’t need to be part of an orthodox Islamic faction. What is ridiculous is your friend expecting to get a “seeta savatari” type as you put it but not thinking that maybe she wants the same for herself. Marriage is a big step and everyone wants a partner who is compatible. If his lifestyle and thinking is the complete opposite to hers why would she marry him? I’m not saying he shouldn’t marry I’m saying he needs to sort himself out and maybe reassess the type of woman he should marry. Maybe he should marry someone like himself. You can’t blame environment society parents and everything else except him for his decisions. He decided to have flings. His parents didn’t force him. And this girl if she has sense won’t marry him. When I got married my only requirement was someone decent who was on my thinking level. And alhumdulillah I got that because the “seeta savatari” types aren’t all that rare.
