UPDATE!! I Iied to my boyfriend and im ready to tell the truth

so when me and my boyfriend started dating he knew i had a bad relationship with my step dad and honestly it was hard getting to where we are today. when we had been dating for i think 2 months around that time I I to confess about a damily member who molested me when I was very young. I dont remember exactly how he came to asking me about my step dad if he ever tried to touch me or anything like that and i lied and said no my stepdad molested me too but I I tokd anyone he used the excuse that he was doing massage therapy and i hated it and he said he wasn't doing it to hurt me he wanted to help and that he wasn't my childhood molester later he put a camera in my bathroom and my mom came in with me that day and noticed it i had no idea it was there I didn't even know how long he had been doing it. he came to my mom with the excuse of that i didn't do anything to communicate with him and her and that he didn't know anything about me it was the only way he thought to know something my mom said she would leave him but they ended up together again and we move to Florida I really support my mom even though I know she is wrong he kept trying to spy on me after we got here and thats why why started staying weekends with with boyfriend so i wouldn't be at home we are trying to move in together now we have been together for a year and i want to be honest with him about my step dad i mean he already hates him for other reasons I just want to be honest with my boyfriend but im afraid he would look at me differently like im some idiot that lets people walk over me and that he is going to be upset that I lied to him when he asked me about it what do yoy guys think I I do? UPDATE!!!............................................. so i tild him and i dont even know what yo think about his reaction he got mad at first understandable but he then told ne that i knew what he was doing and if i didny say anything it was because I likedit i told him before hand that I was going to hey hurt if he said something hurtful he tends to be cruel honest I I him ir wasnt easy to say and why did he think I Iiked It he said that that need to tell my mom and i told him I did and he just nodded his head in disbelief and went on how if his mom did that to him he would cut her out of his life and he said that when we moved in he didn't want to see anyone of my family there and when we had kids that I would not leave them with my parents I am confused and sad I didnt expect this and i mean I guess he is right on somethings but ... what do you guys think?
