TW: Suicidal thoughts

Hey everyone. My ex broke up with me 2 weeks ago due to his severe depression and he just pushed me away.

He doesn't want to go to therapy and isolated himself.

He has tried to stay in contact with me even though I told him we aren't friends, and today we had a long talk and he confessed he is having suicidal thoughts. I can definitely tell he isn't doing good and he is going to go to his mom's (in another city) for a month tomorrow.

Whenever he is there his depression goes through the roof bc his mom is never around for him.

I am deeply concerned because this is the first time he admits this in 2 years and him being alone here and at his mom's worries me.

I want to talk to her and ask her to check up on him or something.

Advice on what to do? I know we aren't dating but I still love him and worry about him as an individual, this isnt about being back together.
