It's like an endless cycle of having my heart broken or me breaking some nice girl's heart. I have to juggle multiple women at once to not waste time because chances are these little games last 1-2 dates. This is ridiculous. If you randomly stumbled across your wife without putting in much effort, consider yourself blessed.
Nobody is saying be friendzoned and thirsty, but talking with women regularly helps one to find a woman.
I'm not saying the friendzone thing is totally wrong, but there were several girls in my group of friends right after college and one of them is now my wife, so you could see how I might have my doubts.
Avoiding befriending women as a way to help find a wife is shooting yourself in the foot. I guarantee it.
But that's not to say you can't be friends. If there's a girl in your friend group and you chat with and flirt with her from time to time but you're not dating most people would still call you "friends". Just not platonic friends.
Also, a lot of girls in your friend group will be with someone, or married. That's ok. While it would be weird to hang out with them alone, if you see them a lot it's still totally normal and healthy to be friends with them. There were a lot of "taken" women that I used to hang out with all the time, and I enjoyed their company.
