Am I putting myself at risk?

I just came out of a toxic abusive relationship about a month ago now and his best friend had no idea what was going on during the breakup until towards the end of the relationship where he started to have arguements with my ex about how I don’t deserve to be treated the way he was treating me and he would stand up for me a lot. He’s always been so nice and considerate towards me and always protected me in a way like he would keep me away from his work friends that can be a bit inappropriate and would make sure I wasn’t in bad situations where I could be hurt or be uncomfortable.

I’ve started talking to my ex’s best friend now and I’ve opened up and told him everything about what my ex did to me. He’s stated that he wants nothing more to do with my ex and he promised he’d do everything he could to prevent such from happening again cause I deserve the world and someone who appreciates how good a person I am and he doesn’t want anyone to hurt me again.

We’ve started to click and things just feel different with him, he makes me laugh, he treats me like I’m a queen, he makes me feel a way I’ve never felt before and I just don’t want it to ever end. My mum is concerned that I’m putting myself in a situation where I could be exposed to my ex and reeled back in to the toxicity. She says she doesn’t trust him cause he was friends with my ex. I just say though that my ex only really ever talked to him when he wants something and that’s about it so there not all that great friends to begin with.
