Trigger warning: this situation will trigger victims of emot

Trigger warning: this situation will trigger victims of emotional manipulation, I think (I have never put trigger warnings before so apologies)

Long post... Apologies in advance...

I honestly can't decide what I'm feeling right now... Things kind of repeated yesterday evening... My brother went out to meet his gf... I assume they had a fight... He went awol... Numbers switched off... unreachable by any means... And there were statuses on WhatsApp saying, "please kill me, I can't bear this pain anymore"... I kept calling his phone and he came into contact 2 hours later and asked me to "shut up and sleep" and that "he'll come when he'll come"... I had a restless sleep and then my mom woke me up in the morning telling me that he locked himself in a room, with the window open and was lying on bed... He's alive... So, I went upstairs to try and talk to him... He refused speaking to me... I just kept going up and down while trying to complete my morning routine and finally got a chair and sat infront of his window...

Then, my mom came and she begged him to open the door... And after begging for a while, he finally opened the door and let only her in... And she begged him again to let me in... And finally he accepted... So, we were both there, and all we got from him is that he wants to die bcs he did some sins and his gf is no longer with him... She kind of made that clear Saturday evening... They were fighting whole night... Him saying he will die and her begging him not to die... Sunday morning, her family got to know and they called him and threatened him with harrassment case... All this happened around 6 AM... My dad, who went to a very important meeting which can't be postponed, came home as early as he can... And then we all - dad, mom and me - told him so much, so many versions and variations... Finally he accepted and had some glucose... And then we brought him downstairs and he slept...

After waking up in the evening, we resumed talking... We said that we're not against his love... But when the girl doesn't want to be with him, there's nothing anyone can do... It kind of went a bit over and we almost painted the girl as bad...almost... But I managed to rein it in... I redirected all such comments (atleast I think all comments)... And he finally accepted (I think he did) to stop talking to her and just give generic responses to her questions...
Now comes the main part... When my dad went upstairs and my mom was asleep, this evening... After all was said and done, that's when I got to know the reason... He said that he behaved very worstly with her... He was very arrogant and he blamed her of adultery while being in relationship with him... He tried to bring another guy into their room... He said that even after that, they both still got a room recently and got intimate... I was shocked to hear that... I was shocked to know that my brother could behave like this... He said that now he realised how much he sinned and that's why he wants to die... Bcs he couldn't live with what he had done...
I told him that, dying is not the way to atone for his sins... He should let the girl live in peace and he should make sure that he won't repeat this mistake going forward... He should try to atone for his sin and that that's what was written in a religious books...
I have two questions... Did I do right in saying those words to him? He seemed really hurt and wanting out of that pain... Or did I just get played? Did he plan this just so he could get sympathy points? I don't want to believe that is the case... But I don't know what to think... I obviously can't share this with anyone... Can anyone help me? Do I forgive him? Can I forgive him?

I think you said all the right things to him. Hopefully he will learn from all of it and realize nothing good comes from those behaviors. Hopefully your brother can get professional help for his depression.
It sounds like it would be best for him not to be in a relationship so he has time to get mental help and get himself more stable.

@Fohb460 thank you… I think it doesn’t matter anymore… I kind of shouted at him yesterday and basically told him that if he keeps insisting on being stupid and stubborn and wants to die, I can’t help him anymore… I think he cut everyone off and closed himself completely as of this morning… I failed… If he dies, it will be on me… But I really couldn’t take being his emotional punching bag anymore… I think I’ll still try to get him help… But I don’t know where things will go now… If it’s written that my family is supposed to fall apart, then so be it… I’m really really tired of everything… I keep slipping back into depression… I keep hurting myself emotionally so that I can be strong infront of him and give him a person to lean on… But leaning on doesn’t mean putting his whole weight on me and expecting me to carry him…does it? I don’t know if I did right or wrong… Like I said, if it’s written that I have to suffer a death and/or a family breakup… Then so be it
