stuck on my past maybe

okay so I'm stressing myself out here SMH I have a 3 year old daughter from a previous relationship I'm now pregnant with another Lil girl from my now boyfriend of 1 year. anyway when I was a child I got molested by my step dad from ages 4 to 8. this eats me alive and I'm terrified of step dads IDK how to get over this. my daughter is so young still but she doesn't act like she doesn't trust him or anything she always chooses to play with him and cuddle him etc IDK it's just my head maybe I don't want to accuse when I really have no proof I'm just scared I don't like to leave her in the room with him nothing and I just started feeling this way Jli guess because we just moved in together. I ask my daughter and she says he don't touch her or anything IDK guys should I bring it up to him even though I have no reason to accuse or is it just me ugh
