My (28F) brother (29M) is blocking my new relationship by deliberately scaring off men with fetish

My brother and I have been raised with foster families, he has been raised in a family completely different from mine and I only got to know him as an adult after a long search.<br><br>I have been single for 1 year and even though I wanted to find a partner, it didn't work out. I am a single mom to a 4-year-old son. By the way, his father cheated on me, I received my son's paternity test last week and to my surprise and disappointment, the child is not his. He said he knew and that's why he left me. I was shocked.<br><br>This week, I met an old acquaintance of mine at the grocery store. We went to school together and became good friends. We lost contact, and after we met, we met up a couple of times and he asked me out. He's a really good person, nice and kind, and he has a 7-year-old daughter. She has been with her mother since they broke up, but we live in the same city, so he sees her frequently. He's a very good father.<br><br>I told all this background because my brother is an element of disturbance in all this.<br><br>I told my brother about my new relationship and he immediately got mad. First he said that I should be focusing on my child instead of a man. I told him that the relationship is new and I'm not going to leave my child alone. My brother said, "What about his daughter? Does she like you?" I don't think my brother has ever been in a relationship, and I think it's just a pointless question.<br><br>He said he didn't trust the man at all. I told him I was a single woman and could decide what I want to do with my life. I didn't even let him finish talking before he interrupted me and said, "This man is a pedophile, he's going to molest my niece or nephew!"<br><br>I was really shocked by his words and told him that he had no right to say anything like that, but he continued to insult him. He said he had to protect his niece or nephew. I hung up on him when he said that he would show up at the man's house and warn him. I told him not to do this and please leave us alone.<br><br>The next day he texted me saying he's coming over to my house. I said no, but he still came without my permission. I was hosting the man at my house and when he saw him, he shouted at him and said, "Don't you dare touch my niece or nephew, I'll show you what kind of man I am."<br><br>I was so embarrassed and confused. I apologized to the man and asked my brother to leave. My brother said that as long as I was with that bad man, he couldn't let me or my son be.<br><br>The man I'm with tried to talk some sense into my brother, but he just insulted him more. After he left and went to his home, I asked the man if he was going to break up with me and he said no, but he needed some time. I said okay and just went home.<br><br>The next day, I received a text from the man saying he couldn't handle the pressure and he had to end things. I asked why, and he said that my brother threatened to send him to jail, ruin his business and destroy him, and he couldn't afford that, so he decided to break up with me. He said he still had feelings for me, but the threat was scary.<br><br>I was so angry when I read his message. I have never been with a man I can trust other than him, he was the only man who showed me love and kindness. My current life is a waste and I live for my son. But he was someone I trusted and loved. I didn't want to lose him and I didn't want to let my brother's behavior ruin my life.<br><br>I called my brother crying and told him what he had done. I wanted him to apologize and I wanted him to leave me alone. He just laughed at me and said, "But he's a bad man, he's a pedophile." and hung up on me.<br><br>I don't know what to do. I'm so sad right now and I'm so angry at my brother. I told him to leave us alone and just live his own life, but he still doesn't listen. I never want to talk to him again, but he's my only family. I have no one else in my life.<br><br>I feel so sad and lonely right now, I'm just crying. I want to just die and end it all.
