URGENT‼️‼️ Should I tell my boyfriend my abusive ex boyfriend has tried to add me on Facebook

So, I was in an emotionally abusive relationship with my ex, who also sexually assaulted me multiple times. My amazing boyfriend knows about it and I have obviously moved on. Now, when I confronted him about it, he basically deflected his actions and didn’t think he did anything wrong. The last time I messaged him, I told him to leave me alone or I’m going to the police. This was in October. We had each other blocked from then on. Now this annoying ass, dumbass whole 20 year old man is adding me on facey. Should I tell my boyfriend? I don’t want him to freak out or think I still have feelings because I feel bad for continuously bringing him up (when explaining what he did to me), the abuse all happened last year and the year before so it’s still fresh
