Please help

So I’m 15, and a close family friend of mine had been being inappropriate towards me.. he’s 29. Grazing his hand against my thigh, asking to take me to my room, telling me he can’t wait until I’m 18 to do “stuff” with me, trying to get me to sit on his lap, trying to get me alone with him, etc. I was afraid and I ended up telling my mom.

She said she understood and would talk to him. I haven’t heard about him in a few weeks, but on Sunday (in two days) he’s coming over to do something with her car, when I thought I wouldn’t have to get involved with him again.

Am I overreacting? I do have some trauma with sexual abuse.. But just thinking about him makes me sick. I just stopped crying when I heard he was coming back over soon. When I say I’m terrified of him, I really am. (He’s yelled at me many times) But he still stays in contact with my family, my mom works with him and sees him everyday and I overheard my sister(in her 30’s) on the phone with him too. (She knows about what happened) and they just talked to each other normally.

They even said that they loved each other at the end of the phone call. So what I’m trying to ask is if I’m overreacting, do I have a right to feel betrayed and as hurt as I do now?
