In my opinion, men and women can never be just friends, its not possible.
Which is why I believe its better to avoid this type of friendship, because it wont work out, plus what will happen when you're married and run into one of your ''friends'' ? That wont end well for you.
It is against nature for men and women to be friends, the only man/woman you can truly be friends with is your spouse and that should happen after marriage because to become good friends with someone you have to get to know them well and once that happens you'll start to care about them which is normal, we all care about our friends so if you're married its not a problem to have feelings for your husband/wife but if its a ''friend'' then that's gonna cause problems.
In Islam there is no such thing as friendship with the opposite gender, so why do we still think we can make it work?
Do you guys think men and women can be friends?
~~~ Peace out ~~~
