Should i talk to his friends?

I broke up with my bf of 6 months and he is not doing very good, im worried, especially if he is drinking alone. Should i tell a friend of his that he might need some company?

i broke up with him because of some weird anger issues he had.He sends me texts all the time (to which i usually dont reply) i woke up to 59 this morning. He talks about suicide a lot and i dont know if he means it or just wants attention, he changes his mind all the time but when he stops texting i get so worried, not because i still want to get back together but it would kill me if he did it. i was very clear that it is over and im not changing my mind. He is just so confusing saying he loves me but he gets pissed at me a lot of times he demanded everything he ever gave me back and i did give it back (even a puppy which i loved that asshole took it back). He might be crazy, his parents are not supportive they are against him. I just dont know what to do, if he is crazy then he really could kill him self.. I moved to a new town and met him and never made friends of my own so i knew i would have nobody to talk to or hang out with when i break up with him but i just could not deal with his "freak outs" anymore. he tells me he understands and doesnt blame me one minute and then tells me im a horrible person for hurting him the next minute. I am just alone and worried i wanna make it easier for him but dont know how (its been like 6 hours since he stopped texting)

It's not about what you do but how you do it and for what reasons. Obviously you still care about him as you would any other person you'd spent a portion of your life with, in which case, of course you wouldn't want him to do anything stupid (despite it's clear he wouldn't, and the threats just a desperate tactic, made all the more credible by the fact he deliberately goes, bam-bam-bam-bam-bam!....SILENCE....). So by all means tell his friend you believe HE should be concerned, but make it clear to friend that you yourself are done, with this your final act for ex THE PERSON'S benefit out of nothing but love in-memoriam and concern for others generally. Trouble is, you're NOT done, are you. Maybe with him-the-boyfriend but not him-the-someone-to-talk-to-and-hang-with. You obviously need to start putting yourself out and about in places where you can make one or more friends (or even in the first instance just people to regularly chat with, like a weekly club or evening class). As for your ex, he does sound like he was/still is abusive and that the reason he felt he could be was BECAUSE you came already isolated. He probably can't handle the realisation that contrary to what he always assumed, he was NOT and could NOT act like he was indispensable to you no matter what he did or how self-indulgently he kicked the cat over his existing woes.

Alternatively, are you perhaps at the back of your mind hoping such a call to his friend might facilitate a connection between he and you (aided by your impressing him with your female kindness and concern) as could possibly develop into friend- or lover-ship?
