This is gonna be long, I apologize. But i need help!!! First, little back story, my mother has been married to my (step)dad for 21yrs. They were highschool sweethearts, until he got into trouble & did 18yrs in prison When I was 6 she rekindled w/him, they married while he was still in prison. A couple yrs latr he was released, they had my lil sis & bro.

When I was younger he & I couldn't even be in the same room w/o it being an all out war. We were both to blame. I of course, wasn't going to listen to someone who 'wasn't my father' & no one was going to tell me what to do. He being a hardass it was his way or no way. So naturally we butted heads. We fought constantly, not just arguing but actual fist fights- I have a scar on my eyelid and he has missing teeth, all as reminders. I couldn't take it anymore for my sake, my sis/bros, & especially my mothers. She was constantly playing referee between us, it was a huge drain on her. So I moved out when I was 17.

Once out of the house we actually started to get along, like there was never a problem between us, he refers to me as his daughter & I him as my father. We are close and have a very strong relationship. Just like father/daughter.

Every year for the past 7yrs we go Xmas shopping together, as he doesn't know what to get people & I always wrap his presents cuz he sucks at it. Well tonight we went late- 10pm cuz of my lil bro/sis wrestling tournament. Everything was fine until we went to dinner...

He said while waiting for our food, 'I really wanna tell you something but I'm afraid....it could make you think differently of me or get me in trouble.' I was like ummm ok? & left it at that. Fast-forward to in the car, he gets out his wallet, he always gives me a couple hundred for 1 of my xmas presents. I start backin up and he goes 'wait... now here's the $300 for your tattoo, but I wanna talk to you' I asked what about. He said, 'now I'll never bring this up again after this and you can never tell anyone it's our secret. But...I'm attracted to you. I always have been but lately its just been on my mind &I'm sure you already know'' I couldn't believe what I was hearing, here is someone i consider my dad telling me this, nver in a million yrs would I have thought! He continues, 'i want you. And i know it's fucked up but I want to have a baby with you. I could give you everything.' I sat in silence for awhile in disarray, finally I screamed 'so this is you asking me to sleep with you???' He said 'well yes, but be with me'! Me, 'you're married to mom, you r suppose to love her...youre like my dad, why? I have never thought about you that way. NO, ABSOLUTELY NOT!' end of discussion I speed all the way home just so I could get away from him, I was completely uncomfortable. He left as I was taking the presents downstairs and my SO comes down & like always asked 'how'd shopping go'. I look at him & instantly broke down. I told him, of course he was pissed & wanted to go over there. I can't really speak to him right now, all he's seeing is red.

Ladies, idk what to do. I know this is highly inappropriate & wrong. I know if this was my SO I would want to know but I don't know if I should tell my mom? I want to but I know the pain this is going to cause her & that this is going to ruin the family, I don't want my lil sis/bro to have to go through what this will cause. What do you ladies think? What would you do? Please I really need some advice i have no one I can talk to about this.

*update*

Thank you ladies for the advice. I told my mom sunday, before we were suppose to have out family dinner. As you can imagine she didn't take it well, but she is hanging in there. I don't know how this is going to effect their marriage, I don't know what the outcome will be. My lil sister and brother have been at my house since sunday(it was world world III @ the house) they are disgusted and said they have lost all respect for their father. He wants the family to still have dinner next sunday, so he can speak with everyone, once he's said what he needs to he said he will leave so we can have dinner, I have not decided if I'm going to attend yet.
