Sharing Our Innermost Thoughts

So I posted this question about this guy I’m talking to yesterday
and I did get a few replies
and this is what happened afterwards
yesterday after posting this question he texted me and I wanted to get over with him asap
I couldn’t say no straight away
so I made up excuses and told I’d be away for few days because of my personal family issues
and he started acting weird
that’s it’s fine you can leave whenever you want I’m just crying and sad and you’re taking away my happiness that I got after my father
and then he threatens me
just be ready to find me in a hospital in two three days and right now too I’m going out on my bike and I can’t breathe and I’m getting unconscious
I jst don’t know if he’s making this all up?
it’s just been 3 days and this guy is making me overthink
am I overthinking ?
or am I being too kind ?
Should I just block him right away ?
