My boyfriend/fiancé used to have sex with his step sister regularly, and it makes my blood boil. Should I learn to move past it?

Question

Hey guys. (I apologize for how long this is)
I’m super new to this, I can’t ask anyone for advice about this unless it’s anonymous. I love my man, We’ve been together for almost 2 years, and in the beginning he had already mentioned that he was a “sex addict”.
I’m typically a very jealous girlfriend, I would probably never willingly have a 3 some but about 6 months ago were were joking about having one. We were drinking that night, and he told me something he had never told anyone else: that he used to fuck his step sister, regularly. I was blown because she was someone I would never expect, because any family occasion or holiday, she is around. She was always nice enough girl, so I never had an issue with her. He said only because they didn’t know each other for long, their parents had only married that year and they originally lived in different states, it was a “I don’t know you, and you don’t know me” Situation, So they thought it was a good excuse to fuck with no strings attached. We were bickering and I brought it up, and he admitted that it was still going on about a week in when him and I first started talking. After it was apparent that he & I really liked each other soon into us dating, it never happened again. Even before he told me this, the thought of them having sex makes my blood boil. I hate her and her face disgusts me. They’re close, there’s obviously still tension there, but he’s not physically cheating on me so I would be the asshole if I got mad about it. He says they’re just friends, and he wants me to be friends with her too. What would you do as a female in this situation? Is it wrong for me to feel hate towards her. Is it cheating if we just started talking? I love my man so much but Sometimes I get so angry thinking about them I just want to end the relationship because for the life of me I can’t get over it! I have never been in this situation before and don’t know how to feel about this. :(

Okey so i read everything and let me tell you something that u can trust your man he does love you the thing is that's in the past he used to sleep with his step sister but when did he stop when you too started to like each other and your relationship started to evolve you have the right to get mad of this but not that much because he stoped if he still sleeping with her thats another matter but he stoped like 2 years ago and the thing is that he told you and respected you and he stoped and told you when and how he stopped rethink about this take a deep breath and let it go its in the past

Well.. he was drunk, so you can never accept someone in that state's word fully. Also, it was his step sister, not sister.

Lastly you're the jealous type, so you're going to make drama either way. Just grow up and move on. Just keep an eye on his whereabouts now and then to ensure he's not backsliding

Yikes that’s awkward. The difficult part is that since she’s a part of his family, they still meet up during family occasions and she’ll always be a part of his life. If he’s overall a great boyfriend, you’re gonna have to learn to accept it (might take a long time and that’s okay as long as you’re willing). If this is absolutely something you can’t get over then it’s better for you to end it asap

He's a weirdo. Dump him. Society needs to disincentivize this type of behavior.

Wise4myage · Answer

If it bothers you that much, then you should think about moving on, or focus on accepting the situation as it is. Its not like he banging her now.

You should break up. It's going to cause nothing but friction in your relationship. And he'll fuck the step sister again.

Can you really get past it? If so, forgive him and get on with the relationship; if not, dump him. Either way, move on.

boobliker · Answer

if you can't you should dump him as it will always be on your mind. best be gone with it..

Mangospacho · Answer

You might want to break things off. If you’re looking at him as someone you like except for the things he is or was, then it’s time to find someone else.

Twalli · Answer

He's not cheating on you. That's far more important than the person he used to fuck.

I have also had sex with my sister once, we were alone in the house and we're young and there was porn on TV accidentally turned on, we watched it and wanted to try it out ourselves so her being much younger than me started to annoy me to show her my dick. After a whole I agreed and did it for hours.
