TW suicidal thoughts

20f broke up w my ex around a year ago. it was a clean split with no contact and i deleted him on all socials. i recently started dating my current boyfriend 20m a few months ago, and all things were going pretty well until my ex had reached out to me again over discord (which i forgot to block him on bc i never use it.)

for context, my ex has a lot of academic pressure as he’s attending my uni on a scholarship and student visa that may be revoked if he doesn’t maintain extremely high grades, and faces immense family pressure for academic and occupational success since he came from a generational line of extremely smart, wealthy, and accomplished people. we go to a prestigious uni w immense coursework and he’s always been incredibly stressed and anxious about school as a result.

he texted me last night asking if he could please call me. i was honestly shocked at the text bc we hadn’t interacted in a year, but didn’t know what to do so i didn’t respond. he texted me 5 minutes later saying he’s been really down the past few months and really needed someone to talk to. he had been doing badly in classes for a semester and his scholarship was on the line, he also got rejected from a master’s program which was his dream school, and he was on incredibly bad terms w his family now. i still didn’t reply just out of shear shock / not knowing what to do now that he was texting me, and just read what he said from the notifications. it was only until he started saying some really concerning stuff about not wanting to be alive that i finally messaged back, because i was scared of what he might do next. he called me and i answered and i basically just comforted him for a few hours. i felt really bad for him because the fact he was reaching out to me probably meant he had no one else to talk to about it. obv we won’t be talking anymore, and i made that clear to my ex as well. i reached out to him only because i literally thought he was going to off himself that night

i told my boyfriend of the situation the following morning, and reassured him that it was just because it was seriously concerning stuff that my ex was saying, and we wouldn’t be taking anymore or anything. he seemed quiet and was definitely upset, and avoided talking to me for a while. like not directly mad at me, maybe just sad that we’d talked again, but now i’m anxious. i want to have a talk with him but im scared. im not sure what else i should have done though, because if i ignored him that night i genuinely don’t know if he would have offed himself. i would want to be there for anyone who was suicidal

aita?
