Do you believe that long term male friendships can last?

I was thinking back to alot of my male mates Ive had and I started realising that alough I have had more guy mates than girls, they were either not as close as initially thought or that alot of them never seemed to last that long. This being due to us losing touch, crushes or complications from relationships with each other or others.
In the end I have stuck with more of my gf as the years have gone by and had stronger/longer bonds with them.

As I once held such a strong view on this idea of u can have real male friends to the point I never thought I would have proper friends with girl(s), i wondered if other ppl agree with that u can have a true friendship with the opposite gender, or if their opinion has changed over time, or if it just a matter of who u meet ect...

This is speaking as a straight female just to give the idea of the perspective as to some of it I have said btw
