<human>: My boyfriend of 4 months tried to kill himself two months ago due to depression and he ended up in uni for about a week and half. Before that,my mom was at one of my games and had overheard some of his friends saying he was doing drugs and I confronted him about it and he told me it wasn't true. 
 
  For the past two days, I've noticed that he has been acting differently and I ended up asking him today if he was doing drugs. He said yes he has been doing for the past two days (according to him) but I think it has been longer. He pretty much said that it was his decision and that whatever he does should not effect me. 
 
  I'm a drug free person and I don't believe in those things. I do sports and it's looked down upon in my family. I don't know if he will change; I told him to get his priorities straight. I don't know if I should stay with him or just leave now before things get worse.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My boyfriend of 4 months started using drugs and I'm not okay with it but he doesn't seem to care much. I don't know what to do!
