Is This Restraining Order Serving Valid?

Me & my fiancee are no longer together. She has deep psychological issues & trauma due to her getting SA by a couple of people including her uncle when she was a child. One of the main reasons it ruined our relationship. She just refused to face that trauma that was causing issues in our relationship.I wanted to help her face that trauma so I spoke to her parents about this but they didn't do anything & they simply swept it under the rug. I also contacted friends & family of hers to get them to try to help her (sort of like an intervention) as well but to no avail. Until recently one of her friends reached back to me & wanted to meet in person to discuss about the situation that happened to my ex. She decided to meet in a restaurant, so when I got to the place to meet her friend it wasn't her, it was her friend's sister & her boyfriend (ex's cousin who's also the son of the uncle that SA her). He placed some documents on the table & said it was a RO. Since it was a set up I didn't say anything & simply left without accepting anything. I'm positive for the RO is that my ex & her family don't want me to keep exposing that uncle since it seems that they're protecting him. So my question is, can he serve me a RO if it's a conflict of interest? The circumstances aren't neutral if he served me while being the son of that uncle who SA her & him being her cousin as well. He's is not a unbiased third party that's not related to the case. Was that serving valid or even legal? This took place in the state of California. Any help or legal advice on this is greatly appreciated.

Notes: After the break up I did not stalk her or ever showed up to her house uninvited, never laid a hand on her or anything of the sort. I haven't contacted her or anything in weeks because I had decided to give up trying to help her. I can't help someone that doesn't want to help themselves. I only met with her friend to answer any questions she might have since I thought she genuinely cared about helping her.
