AITA for telling my family I'm married now after they demanded I take care of my brother's kids so he could marry another woman?

I F33 had a long term boyfriend for years. We have two kids, M6 and F8. He is from the Middle East and has been clear he wants to marry someone from the same place he is from. After our second child, he and I were talking about our future and the fact that I am not Muslim was a big problem for him and I knew that. We discussed and he went back to the Middle East for a month where he was to be married. <br><br>He is a nice person and was understanding and said that we would be married when I was ready. After he came back, I felt I was ready to get married to him but he said that he did not want to change his religion and that would make it hard for us to get married. So I simply went to the court, changed my religion, and got married to him. <br><br>I did not tell my family about any of this. For months I was telling them I was dating him but now I simply told them that I was married. I also told them that the kids were now his. They were shocked that I would do something like this and said I was insane. I told them I was ready to get married and so it was all good. They said I was crazy and that I was being disloyal to them and the family and that I was insane to marry someone that did not even love me or wanted to be married to me. I said I didn't care and that I was married now and happy.<br><br>Now comes my brother and his family into the story. He F42 was in a relationship with a woman for over a year and she recently got pregnant. According to him, he was drunk when he had sex with her and did not wear protection. He says that he is not the type to ever cheat on his wife and that it was a mistake. Unfortunately, the woman was demanding that he marry her. He came to our parents asking for help and they said they would not help him. He went to his in-laws and said that he would gladly marry her but only if she agreed to abort the baby. She would not agree and so he came to talk to us and I told him that I heard about a place where he could go and get out of this situation legally so he went there. Now the family is talking about this and saying that I am a hypocrite because I did the same to him and so it is all my fault. They want me to tell him to marry the woman or abort the baby and he won't do either so I have to force him to. <br><br>I told them to fuck off. I said they have no right to tell me what to do and that this is his decision and he will do what he wants. I said that we all have the right to decide what to do with our bodies and that there was no need for me to control him or make him do anything he didn't want. Aita?<br><br>Edit: I am not 33. I am 33 - 6 - 8 = 19.<br><br>Edit 2: My partner did not cheat on me. I am well aware of the fact that he is not in love with me and I see us as friends. This was a long time coming and I was ready so I did it. <br><br>I was never in a relationship with this man. I am not in a relationship with him now. I am his friend. He is my friend. I am not jealous of him, nor do I feel like I am forced or obligated to do anything for him. <br><br>If you do not understand that you can fuck right off. It is not hard. I am not in a romantic relationship with him. I am in a friendship with him. A romantic relationship is not the only type of relationship that a human can be in. Humans can be in many types of relationships. <br><br>Stop projecting your insecurities on me. I am not insecure and I am not jealous. If you are jealous and insecure because you are in a relationship that is not going well then maybe you should address that instead of projecting them on random women on the internet.
