Ex boyfriend is really distressed

[HelpHelpHelpHelp1]

Hello!
We're both 25.
I broke up with him over long distance at the start of the year and i'm with someone new and have been with him for about 2 months.. ex and I were together 5 years.

Ex has come home from travels.
He came home this week. He is texting me asking me to meet up and speak to him. I've refused. He's texting me saying how much he loves me and wants closure.
I had a phone call with him tonight to try and give him that closure, He was begging me to come see him, said he was parked around the corner from my house, started crying, said he'd had suicidal thoughts.

I told him i'm with someone else and he said "all couples go through hard times, we can get through this.

I ended up ending the call because i got overwhelmed.
He messaged me saying he was still around the corner of my house and i can come sit with him in the car - i refused.
He's texting saying i'm the love of his life and he just wants to soeak to me for 5 minutes then he's out of my life.
He's texting me memories we've had together and how he's never going to be with anyone else again, how i'm the love of his life.

I was going to block his number until he brought up the suicidal thoughts!
I've text his mum to say i'm worried,
But i dont know what to do!!

He sounds deranged, HelpHelpHelpHelp1 but you've done all the right things. Take no notice of Bently, who doesn't seem entirely stable either.

How has your week been OP?

Life tip #1 as the others have said- if anyone mentions suicidal ideation, call the police immediately. #2 This is stalking, if you get any further contact from him, call the police. They will have a word with him hopefully, and that'll make him back off. Glad you're starting to block him on stuff. If he contacts you through any site, email or whatever, block immediately.

I can't reiterate enough that if someone mentions/threatens suicide to you again, you must call the police or you're not doing the best you can to help them- it's an emergency.

That also calls the bluff of anyone who's saying it to be manipulative (unfortunately some people do) and it hedges your bets just in case they are genuine. Hope this helps. Xx
