Is it just me or is it difficult establishing a friendship with people these days?

I was born in 78, but of course things have changed since the 1990's. It seems alot more difficult establishing friendships as an adult than it does when you are younger. In my case, alot of my friendships have failed because I don't tolerate disrespect. Things like talking behind my back or speaking bad about me to impress a woman or friends that they (my so-called friends) currently hang with. Another thing is lying or trying to use me and when I lash out about it, I'm then considered the bad guy. I think my question is: ARE THERE ANYMORE DECENT PEOPLE LEFT IN THE WORLD WITH GOOD MORALS AND VALUE THEIR FRIENDSHIP WITH PEOPLE THEY CONSIDER FRIENDS? It seems like nowadays, the only motivation people establish friendships is to get over or use the individual in some way. needless to say, I don't have any friends but have things changed THAT much? Or maybe it's just me.
