I've suspected my 17 year-old cousin was stealing from me, but tonight, I found absolutely irrefutable proof. He used to steal a few bucks here and there when it was much younger, but after I caught him and gave him a solid yelling-at, I wanted to believe that it was all behind us.
Now, the item that I know 100% he stole (and subsequently pawned-off) was Halo Reach; not a bad game by any means, but clearly not worth a ton of money. I'm angry, though, for two reasons.
First is the obvious; the fact that the motherfucker stole from me. My sister and I have basically raised him and his sister, as his dad's in jail and his mom has some other kinds of issues. While he doesn't live with us, we've always made sure that they were taken care of, and constantly went out of our way to try and feel like "family". The fact that he is still comfortable stealing from me is simply unforgivable -- I've already given him a second and third change.
Then there's the other issue; I think he may have broken-into my mother's house last year, when her HDTV and my PS3 were stolen. He's one of a few people who would have known the place was vulnerable in the few days after mom had traveled out-of-town, and while I have no hard evidence to prove it, I've long suspected it anyways. As well, I've often been made fun of in my family for having a notoriously bad memory, and I've seen him frequently play things off as "Oh yeah, I gave that thing back to you already". Case in point; I loaned him a case of tools about two weeks ago, and he claims he returned them last week.
I've grown up with a pretty shitty family, I've been bullied by my older cousins, beat the hell up, all kinds of shit -- but this is just a new low. This is someone that, even when I was a kid, I was taking care of, trying to be good enough family that I never even had, despite only being about 8 years older. I've tried to give him the benefit of the doubt, hoping if I treat him well that he would turn out a good person, but I really just feel gutted. How should I confront him about this, and is there some kind of repercussion I should be suggesting for him to his mother? Or is it better that I simply cut him out of my life completely?
