how common is getting betrayed by people I wonder?

I wonder if I'm too paranoid outside of typical statistics because of subjective experiences

like learning some rich elite chick's sister was married to a hacker... and the hacker helped her family. and I'm here sitting like. I dated a hacker once. I felt like he wanted me to incriminate myself so he could blackmail me into marriage (he shared with me that that's how his parents were together... probably forgot he shared that). I got too paranoid and started talking to him less after that lol. though to be fair he never did do anything malicious against me, just dumb childish things sometimes

I think a lot of people just don't betray you because they just don't have the means by which to do it, too. like they just can't comprehend ambition, not that they're actually loyal to you. but this also makes them pretty lame pack-mates

I was too paranoid to take workplace related "opportunities". like someone inviting me to another job. because during computer science all the dudes would try to con you into going out with them or for nudes. so they'd say they have something you want so they could drag it out and then "negotiate" so that caused trust issues in me in regards to job networking. if a guy won't even show you his homework that he got a good mark on and you didn't on yours, and I just wanted to know what the teacher was actually looking for, would be hell in terms of jobs where you're bound by contract and monetary dependency, and any notion of pushing back is insubordination (nor does HR ever work, I found for toxic workplace stuff). so you're fucked if you're "close" to some dude enough for him to actually want something like that from you to where he's devising these things, or if he thinks you owe him because you "only got the job because of him", in my mind anyway

is it as grim as I think?
