I had a really good friend (let's call him X). We were the kind of friends which teachers would call inseparable.
We went to the same school, the same private tuition and then hung out for some time. We were practically apart only when we were sleeping or doing homework (that can't be done together).
Last year we had a group of 5-6 students, who attended the tuition in our slot. We all got very close over time and became good friends. There was a girl too in that group. She was very pretty, and X had a crush on her. They met on Facebook and eventually got in a relationship. I was happy for him...but we spent no time together anymore, barely an hour a day, and in that time he used to talk about her. I mockingly used to ask him to just stop talking about her, he did. I never complained, and made most of the time we had.
Things got out of hand when he was close to flunking out of class. (We were straight A students, sorry for bragging.) His parents found out about them, and gave him another chance. Next time, he barely passed the exams, so parents made sure they never met. They still talked once in a while on borrowed phones. I was always there for him, but he never appreciated that I still supported him. He never wanted to see me anymore, and this time I was annoyed.
We talked sometimes but not like before. A few days ago, he called me at 3 in the morning about how he feels towards life and it has no meaning for him. I sensed the situation and tried to console him. We were on the phone for like 2 hours.
I am worried for him. How can I make things right again? Basically, how can we start hanging out again just like before?
For reference I am a 17 year old Indian.
