<human>: I [18] previously broke up with my boyfriend [18] of around 18 months, after doing so he sent me a series of messages claiming that he wished he'd gotten me pregnant, then continued to tell me that he wanted to beat me to death with a hammer then kill himself and be with me forever.

I know it's creepy but he said this at around 3am in a flood of emotion so I'm doubting whether to actually make any move towards the law/police. I live in the UK so I'm unsure they'll actually be able to do anything but it's been haunting me for a while since it happened.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Teenage ex boyfriend threatened to kill me to be with my forever, should I be alarmed or does this sound like the typical attention seeking type thing?
