So you can’t stay “pure” and “nice” if you are dating? There’s many people who married after dating and they have a successful marriage and life. Besides not everyone dates 5-7 years. It’s usually 1-3 years.
so after 1-3 years you find out that you are not compatible with your partner even tho you shared emotions, feelings etc (gf bf stuff) then you will break up? and find a new one? is that being pure? you are diamond or a gem, stay hidden and untouched, your perfect match will eventually find you out thats how nature rolls thats how God Almighty plans. pious men will get pious women sinner men will get sinner women, vice versa. Remember whenever there is a heart break, people gets sad then they went through remolding in a such way that Fuck being nice, be a badass, fuckboy or fuckgirl and start enjoying and chain continues, victim will do that again thats how Satan play rolls, his way of trapping is time taking and deep. dating is like double edge sword. dating is for boys and teenage (emotional and hormonal brains) marriage is for man (Rational). Choose your woman according to what your Islam tells you (best decision ).
You can’t really know that a person is nice or well-mannered without dating them because some of them pretend and you can’t pretend forever
i have seen many relationships, 5 7 years long but eventually those ended up, wasted time, got hurt, went into depression, destroyed their career etc. they were not pretending fake. its not necessary that only by dating you get to know each other. for this issue, islam gives best solution and that is stay pure and be nice, you will get a nice and pure partner.
Dating is not allowed in Islam, i can give you reasons why? but it will take much time. Dating is not the only thing to know other people. you have to involve elders they have more experience than us they understand, they choose the best one for you. will you keep on changing your date unless you find one? lol. why dont you marry someone who is inside out very nice mannered respectful and respectable and then you after marrying her him, dig out one by one characteristic of each other, start getting to know eachother slowly and gradually fall in love with your spouse, and you will surely enjoy.
