I slept with my boyfriend's ex sister in law. I don’t know how to tell my boyfriend.

The title is really rocky and not a joke at all. Everything was a mistake and was not on purpose. I am 44 year old divorced woman. I have a son.





I moved here in this small town about 29 months ago. I moved here because is very near my son's boarding school. About 27 months ago i started dating this divorced guy. His ex wife is an addict. She is addicted to cocaine. In 2018 she was sentenced to 3 years in prison for credit card fraud. They divorced. She served 2 years. My boyfriend has full custody of his daughters.

About 15 months ago i started having sexual experiences with other women. I love my boyfriend to death. He's the most sensitive, caring person that I've ever come across. My boyfriend is okay with me actually being with a woman or having sex with one. he says it is not cheating and explains that he does not get jealous over women , the reasoning being that he's not that well-versed and educated in sexuality. his distrust in men in general (being pushy with flirting, pursuing, etc.) is what makes him feel more jealous. My boyfriend is extremely jealous of guys, even the ugly ones! "If ANYONE could steal my big ebony girl, it would surely be another man" he says often. .

About a month ago my boyfriend's ex sister in law moved back here in her hometown. She is a 43 year old short skinny mousy pale divorced bisexual woman. 5 days ago she walked into my store. She was really friendly and so was I because I wanted to make sure that I was cool with my boyfriend's daughter's aunt. . After talking for a while we swapped numbers. Nothing serious. The next day she texted me.

We decided to meet up again and get some coffee. I told my boyfriend me and his ex sister in law were hanging out and he was ok with it. After we got some coffee we walked around and we both went back home. I decided to go to this neighborhood women's party that night. When I went with some friends I saw this woman my boyfriend's ex sister in law. She was with some of her friends. We made eye contact and she walked up to me. After a few cocktails my memory and vision were very blurry. I asked her if she could give me a ride because my friends weren’t ready to leave. She agreed. When we were driving she needed to get something from her house and I needed some water so we both went in. When we were in she started groping me and kissing me and I kissed her back. We soon went up to her room.

I don’t know how to tell my boyfriend. My boyfriend is okay with me actually being with a woman or having sex with one, but this is differen't . She is his ex sister in law. And he kinda hates her. Also she is his daughter's aunt , and they kinda hate me. My boyfriend’s daughter's nickname for me is giant overdressed cow. They are very rude to me. His daughters ignored me for a while and then they started to be very rude. They would make offhanded comments about me, insult me, and told me that I am a giant , arrogant, overdressed cow. They tend to just call me a giant cow.

I don't see the issue with the sex part of all that, or the person either, if you like her, who cares what others think.
Those abusive children though, that is disturbing, maybe talk to him about that and try to figure out a way to get on their good side so they start being nice for a change.

@JamesBugman thanks for your support. My boyfriend is very protective of his daughters, because of the whole situation with his ex wife.
