Things who is HARAM

Dating is HARAM....Chatting with non-Mahram is HARAM... Just think for a while, if you were to pass away right now, this is the state in which you're going to see your Allah. You did not trust Him to find you your man. You did not believe in Him??? You did not love Him enough to give up haram. You chose someone else over Him. Do you honestly believe it's gonna work out without His blessings? You might wanna make it halal eventually, but who promised you tomorrow? Even if our cause (target) is noble we CANNOT use haram sources to reach there. (i.e. we cannot give charity from stolen money, we cannot have an affair to get married, etc). So why chatting, dating, gossiping, friendship with non-mahram ???
