I'm not a part of my friend's life anymore
 

Guys, I need your advice. My friend stopped talking to me since he got himself a girl, so I don't know how to get a friend back.

That's a really bad friend. You need to talk to him, or just find yourself a new friend that won't leave you.

What kind of advice? Do you think it's so easy to find a new friend? Don't listen to him. It's just that your friend is in a state of euphoria right now. This will pass and he will realize his mistake. In the meantime, you can find a girl for yourself to also have a great time, try here to read about different dating sites. Good luck to you!
