i think my mom chose her boyfriend over me

This crazy narc, mom’s boyfriend who came in the picture in my late teens kind of ruined my life. Im 22f now. He decided he did not like me and encouraged her to stop talking to me, do not invite me to anything, do not buy anything for me because I do not like him and she listened. I heard him yell at her to pick him or me. 😄. Hes a random loser off a dating app. He is literally crazy and has rage tantrums everyday. He has never been married or had children, its a 66 year old man. Just unstable relationships. He controls every aspect of her life. If I see her he is calling and takes away from any time I spend with her. I just made it clear I really hate him because how would I not and now I’m just ignored. Like who even is this guy and why is he the most important? I know the term narcissist is used kind of loosely but I do believe this person actually has that. He fully changes form to outsiders and everyone thinks hes this lovely guy. My actual dad has not seen me for 7 years. My dad is literally still nicer compared to this guy. I feel so so depressed and like I don’t have anyone that cares about me.
