Would you what your child to be friends with a recovering drug addict *Update*

This post may sound a little familiar but my son made friends with girls at his school. He's been out of school for a year and a half because his freshman year of school he and his friend were attacked in the woods and held at knife point by this weird guys who lived in the woods. His friend got away and my son was SA'd by them over and over again for 6 hours. We were all out looking for him and a neighbor found him completely naked. My son's school let him do school from home while he healed but they said he had to come back this time for the spring semester. He didn't have enough credits to be considered a Junior so he's taking mainly sophomore classes. He didn't want to go back to school. He wanted to get his GED because after it happened not a single one of his friends checked up on him and they basically abandoned him. And this town is small and everyone knows so it was hard. I told him to give the spring semester a try first and the first couple a weeks were bad but then he made friends. Girls. It started with a girl named Bridget sitting with him at lunch out of nowhere and she became his friend then started inviting him to hang out with her friends and at first I didn't like my son being friends with only girls. I was scared he would be having sex with them but I have came around a bit and even allowed him to stay the night at Bridget's house given he would sleep in the room with her brother.

So this is a small town. Bridget moved here last year and it recently started going around that Bridget had been to rehab for a drug addiction problem. My friend told me about it and that Bridget relapsed at her old school because a video of her having a threesome with 2 guys got exposed. She was 15. And the video has circled it's way to our town and not just the video. Her nudes and everything. My friend also asked me if I wanted to see because her daughter sent it to her. She's one of those mom's who are best friends with their kids. I said fuck no that's child porn. And maybe I just let her get in my head but she said it's clear Bridget is only friends with my son so she can get pregnant with his baby and then my family is forced to move her in since she lives in a shitty home with her dad across the tracks. I said my son isn't having sex with anyone of his friends and she said "Can you really think of one reason why Bridget who's clearly a slut would make an effort to befriend your son who had no friends? She wants to get knocked up". I know. My friends stupid but I did talk to my son about Bridget and I was upset that he knew she went to rehab for a drug problem and didn't tell me. He didn't think it was important because she's sober and knows he won't hang out with her if she does drugs and that she's been sober for almost a year. I said he doesn't know that and he said well he doesn't care what I think about her and she's his friend and he's not gonna abandon her when everyone's calling her a slut after she was there to be his friend. I told him to be honest and asked was he sleeping with her and he got so mad and said no and that I made him come back to school and talked about wanting him to get friends and now that he had them I'm complaining. Honestly I like Bridget. She's a sweet girl. But clearly a damaged girl with baggage and problems. Would your son or daughter being friends with someone he had a drug issue was recording themselves having threesome's at 15

@Penelope insulting me isn't answering my question

Update: The girls usually come to my house and I drop them and my son off at school. Bridget was the second to arrive. I asked if I could speak to her in private and asked how she's doing and she said she's coping. I told her I knew about the stuff at her old school and was just checking in and she said "Well I'm the schools whore now." I apologized for what's going on and she said she's used to it but tired of being harassed and she keeps getting people sending her her nudes or calling her a slut. And she showed me a lot of nasty texts. One that made me really angry was someone mentioning my son saying "Guess you and Randy are good friends. You can both say you've been fucked in every hole" but she defended tf out of him. I told her if she needs anything just tell me. And thanked her for being a good friend to my son. She told me when she heard at school about what happened to him she was surprised everyone was staring and not being there for him which is why she decided to introduce herself. I dropped them all off at school a few hours ago and I felt bad for her because someone yelled "Nice Boobs!" At her but I watched my son and the other girls flip him off. I think Bridget and the other girls are good for him. And I feel dumb for letting my friends get in my head.
